Description
Verfahren zur Herstellung eines Kondensationsproduktes.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden- sationsproduktes der Formel

Eine Ansführungsform des erfindungsgemässen Verfahrens besteht darin, dass man 4-Fluor-anilin mit Phosgen reagieren lässt und das erhaltene 4-Fluorphenyl-carbaminsäure- chlorid mit 2-amino-4-trifluormethyl-3', 4'-di- chlor - 1, 1'-diphenylthioÏther-6'-sulfonsaurem Natrium umsetzt. Dabei arbeitet man vorzugs- weise in Gegenwart einer tertiären Base als Kondensationsmittel. Pyridin oder Chinolin sind für diesen Zweek vor allem geeignet.
Des weiteren kann man 4-Fluor-anil. in mit Phosgen bei erhöhter Temperatur umsetzen und das erhaltene 4-Fluorphenyl-isocyanat mit ?-amino-4-trifluormethyl-3', 4'-dichlor-1, 1'- diphenvltlhioäthen-6'-sulfonsaurem Natrium zur Reaktion bringen, wobei man die Verbin dung der obig'en Formel in guter Ausbeute und vorzüglieher Reinheit erhält. Als Lo sungsmittel eignet sich für diese Art der Umsetzung vor allem Acetonitril.
Schliesslich besteht eine Ausführungsform darin, dass man 4-Fluor-anilin mit einem Ha logenkohlensäureester reagieren lässt und den erhaltenen 4-Fluor-phenyl-carbaminsaureester mit 2-Amino-4-trifluormethyl-3',4'-dichlor-1,1'diphenylthioäther-6'-sulfonsaurem Natrium umsetzt.
Als Halogenkohlensäureester kommen hauptschlich niedere Alkyl-oder Arylester in Frage. Der Umsatz kann vorteilhaft in Wasser vorgenommen werden.
Das neue Kondensationsprodukt bildet ein lielles, in hei¯em. Wasser klar lösliches Kristallpulver, das als Mottenschutzmittel verwendet werden kann.
Beispiel 1 : a) 300 Teile trockenes Benzol werden bei 70 mit Phosgen gesättigt ; dazu wird unter Rühren und Einleiten von Phosgen eine Losung von 100 Teilen 4-Fluor-anilin in 300 Teilen trockenem Benzol bei 65-70 zugetropft. Nach einiger Zeit erhitzt man bis zum R ckflu¯ und leitet so lange Phosgen ein, bis nur noch kleine Mengen des verwendeten Amins ungelöst sind. Die benzolische Lösung wird hierauf filtriert, das Benzol abdestilliert und das 4-Fluorphenyl-isoeyanat fraktioniert.
Kp60 : 90 ; Ausbeute : 70%. b) 14, 66 Teile 2-amino-4-trifluormethyl- 3', 4'-dichlor-1, 1'-diphenylthioÏther-6'-sulfonsaures Natrium werden in 60 Teilen Aceto- nitril gelost, mit 4, 57 Teilen 4-Fluorphenyl- isocyanat versetzt und sieben Stunden auf dem Wasserbad erwärmt. Die Reaktionslösung wird filtriert und das Lösungsmittel verdampft. Ausbeute : 12 Teile.
Das Kondensationsprodukt wird in 2500 Teilen Wasser von 80-85 gelost, mit wenig Tierkohle versetzt und heiss filtriert. Nach Zugabe von 150 Teilen gesättigter Kochsalzl¯sung scheidet sich das Kondensationsprodukt aus.
Naeh dem Erkalten wird es gesammelt und im Vakuum getrocknet. Um es von Koehsalz zu befreien, kann es aus absolutem Alkohol ausgezogen werden. Das neue Kondensationsprodukt bildet nach dem Trocknen und illah- len ein helles, in heissem Wasser klar l¯sliches Pulver.
Beispiel 2:
Das aus Phosgen und 4-Fluor-anilin in einem troeleenen inerten Lösungsmittel. her gestellte 4-Fluorphenyl-carbaminsäurechlorid ergibt unter Zusatz von Pyridin als Konden sationsmittel mit 2-amino-4-trifluormethyl- 3', 4'-dichlor-1, 1'-diphenylthioatlier-6'-sulfon- saurem Natrium den in Beispiel 1b) beschriebenen Harnstoff in befriedigender Ausbeute.
Beispiel 3 : Der aus Chlorkohlensäurephenylester und 4-Fluor-anilin in trockenem Pyridin hergestellte 4-Fluorphenyl-carbaminsäurephenyl- ester liefert durch Umsetzung mit 2-amino-4 trifluorm. ethvl-3', 4'-dichlor-1, l.'-diphenylthio- äther-6'-sulfonsaurem Natrium in heissem Wasser den in Beispiel l & )beschriebenen Harnstoff ; anstatt des 4-Fluorphenyl-carb- aminsäurephenylesters kann auch der entsprechende Methylester verwendet werden.
Process for the production of a condensation product.
The present patent relates to a process for the production of a condensation product of the formula
EMI1.1
characterized in that 4-fluoroaniline is allowed to react with a halogenated carbonic acid derivative and the reactive carbamic acid derivative obtained is reacted with sodium 2-amino-4-trifluoromethyl -3 ', 4'-dichloro-1,1'-diphenylthiother-6' sulfonic acid .
One embodiment of the process according to the invention is that 4-fluoro-aniline is allowed to react with phosgene and the 4-fluorophenyl-carbamic acid chloride obtained is treated with 2-amino-4-trifluoromethyl-3 ', 4'-dichloro-1, 1'-diphenylthioÏther-6'-sulfonic acid sodium converts. It is preferred to work in the presence of a tertiary base as the condensing agent. Pyridine or quinoline are particularly suitable for this purpose.
You can also use 4-fluoro-anil. react in with phosgene at elevated temperature and the 4-fluorophenyl isocyanate obtained with? -amino-4-trifluoromethyl-3 ', 4'-dichloro-1, 1'-diphenvltlhioäthen-6'-sulfonic acid sodium to react, whereby one the compound of the above formula is obtained in good yield and excellent purity. The most suitable solvent for this type of reaction is acetonitrile.
Finally, one embodiment consists in allowing 4-fluoro-aniline to react with a halogen carbonate and the 4-fluoro-phenyl-carbamic acid ester obtained with 2-amino-4-trifluoromethyl-3 ', 4'-dichloro-1,1' diphenylthioether-6'-sulfonic acid sodium converts.
Mainly lower alkyl or aryl esters are suitable as halocarbonic acid esters. The conversion can advantageously be carried out in water.
The new condensation product forms a lielles, in heīem. Water-clear soluble crystal powder that can be used as a moth repellent.
Example 1: a) 300 parts of dry benzene are saturated at 70 with phosgene; To this end, a solution of 100 parts of 4-fluoro-aniline in 300 parts of dry benzene at 65-70 is added dropwise with stirring and introduction of phosgene. After some time, the mixture is heated to reflux and phosgene is introduced until only small amounts of the amine used are undissolved. The benzene solution is then filtered, the benzene is distilled off and the 4-fluorophenyl isoeyanate is fractionated.
Bp60: 90; Yield: 70%. b) 14, 66 parts of 2-amino-4-trifluoromethyl-3 ', 4'-dichloro-1, 1'-diphenylthioÏther-6'-sulfonic acid are dissolved in 60 parts of acetonitrile, with 4.57 parts of 4- Fluorophenyl isocyanate is added and the mixture is heated on a water bath for seven hours. The reaction solution is filtered and the solvent is evaporated. Yield: 12 parts.
The condensation product is dissolved in 2500 parts of 80-85 water, mixed with a little animal charcoal and filtered hot. After adding 150 parts of saturated sodium chloride solution, the condensation product separates out.
After cooling, it is collected and dried in vacuo. In order to rid it of Koehsalz, it can be extracted from absolute alcohol. After drying and washing, the new condensation product forms a pale powder that is clearly soluble in hot water.
Example 2:
The one made from phosgene and 4-fluoro-aniline in a dry, inert solvent produced 4-fluorophenyl-carbamic acid chloride with the addition of pyridine as a condensation agent with 2-amino-4-trifluoromethyl-3 ', 4'-dichloro-1, 1'-diphenylthioatlier-6'-sulfonic acid sodium in Example 1b ) described urea in satisfactory yield.
Example 3: The 4-fluorophenyl-carbamic acid phenyl ester prepared from chlorocarbonic acid phenyl ester and 4-fluoro-aniline in dry pyridine gives trifluorom by reaction with 2-amino-4. ethvl-3 ', 4'-dichloro-1, l'-diphenylthio ether-6'-sulfonic acid sodium in hot water the urea described in example l &); instead of the 4-fluorophenyl-carbamic acid phenyl ester, the corresponding methyl ester can also be used.
