Description
Verfahren zur Herstellung von substituierten Aklkylaminen
Durch die belgische Patentschrift 588 736 sind Verbindungen der allgemeinen Formel:
EMI1.1
bekannt geworden. In dieser Formel bedeutet R' Wasserstoff, eine Hydroxylgruppe, ein Halogen oder eine niedere Alkylgruppe. R" ist Wasserstoff oder eine Methylgruppe. Alk bedeutet eine niedere Alkylgruppe mit 2 oder 3 C-Atomen, und X ist eine Hydroxylgruppe oder Chlor oder Brom. Diese Verbindungen haben eine zentralstimulierende Wirkung.
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Verbindungen der Formel:
EMI1.2
In dieser Formel bedeutet R' Wasserstoff, eine Hydroxylgruppe, ein Halogen oder eine niedere Alkylgruppe. R" und R"' sind niedere Alkylgruppen mit 1 bis 3 C-Atomen, die auch zu einem fünf- bis sechsgliedrigen Ring geschlossen sein können. Alk ist eine niedere gerade oder verzweigte Alkylengruppe mit 2 oder 3 C-Atomen und Hal ein Halogenatom. Das Verfahren ist dadurch gekennzeichnet, dass man eine Verbindung der Formel
EMI1.3
mit einer Verbindung umsetzt, die fähig ist, eine aliphatische Hydroxylgruppe durch Halogen zu ersetzen.
Verbindungen der vorstehenden Formel II können bei spielsweise erhalten werden nach dem Verfahren des
Patentes Nr. 403 797.
Als Halogenierungsmittel für das erfindungsgemässe
Verfahren eignen sich z. B. Halogenwasserstoffsäuren in Gegenwart oder Abwesenheit von Katalysatoren (z. B. Zinkchlorid, konz. Schwefelsäure) anorganische
Polyhalogenide, wie Phosphorpentachlorid, Phosphor trichlorid, Thionylchlorid, Phosgen, Phosphoroxy chlorid, Sulfurylchlorid und dgl.
Die nach der Erfindung hergestellten neuen Ver bindungen wirken zentralstimulierend und appetit zügelnd.
Beispiel 1
15 Teile 1-(p-Chlorphenyl)-2-methyl-2-oxyäthyl- amino-propan werden in 100 Teilen Chloroform gelöst, die Lösung mit Salzsäure gesättigt und zum Rückfluss erhizt. Dann lässt man 12 Teile Zinnchlorid zutropfen und kocht eine Stunde lang. Anschliessend wird zur
Trockene eingedampft und der Rückstand aus Isoprop anol mit Kohle umkristallisiert. Man erhält 12 Teile l-(p-Chlorphenyl)-2-methyl-chloräthylamino-propan als
Hydrochlorid. Der Schmelzpunkt liegt bei 179-1800 C.
Beispiel 2
Setzt man 16 Teile l-Phenyl-2-methyl-2-oxyäthyl- amino-propan in 100 Teilen Chloroform mit gasförmiger Salzsäure und mit 15 Teilen Thionylchlorid in gleicher Weise um, wie in Beispiel 1 beschrieben, so erhält man 12 Teile 1 -Phenyl-2-methyl-2-chloräthylaminopropan-Hydrochlorid mit dem Schmelzpunkt 180 181" C.
Beispiel 3
Bei Verwendung von 1-(p-Methoxyphenyl)-2-meth yl-2-oxyäthylamino-propan und gleicher Verfahrensweise wie in Beispiel 1 wird 1-(p-Methoxyphenyl)-2 methyl-2-chloräthyl-amino-propan-Hydrochlorid mit dem Schmelzpunkt 198-199 C erhalten.
Beispiel 4
Bei Verwendung von 1-Benzyl-l-oxyäthylamino- cyclohexan wird analog zu Beispiel 1 l-Benzyl-l-chlor- äthyl-amino-cyclohexan vom Schmelzpunkt 205-2060 C erhalten.
Process for the preparation of substituted alkylamines
The Belgian patent specification 588 736 gives compounds of the general formula:
EMI1.1
known. In this formula, R 'denotes hydrogen, a hydroxyl group, a halogen or a lower alkyl group. R "is hydrogen or a methyl group. Alk means a lower alkyl group with 2 or 3 carbon atoms, and X is a hydroxyl group or chlorine or bromine. These compounds have a central stimulating effect.
The present invention relates to a process for the preparation of compounds of the formula:
EMI1.2
In this formula, R 'denotes hydrogen, a hydroxyl group, a halogen or a lower alkyl group. R "and R" 'are lower alkyl groups with 1 to 3 carbon atoms, which can also be closed to form a five- to six-membered ring. Alk is a lower straight or branched alkylene group with 2 or 3 C atoms and Hal is a halogen atom. The process is characterized in that a compound of the formula
EMI1.3
with a compound capable of replacing an aliphatic hydroxyl group with halogen.
Compounds of the above formula II can be obtained, for example, by the process of
Patent No. 403,797.
As a halogenating agent for the inventive
Methods are suitable e.g. B. hydrohalic acids in the presence or absence of catalysts (z. B. zinc chloride, conc. Sulfuric acid) inorganic
Polyhalides such as phosphorus pentachloride, phosphorus trichloride, thionyl chloride, phosgene, phosphorus oxy chloride, sulfuryl chloride and the like.
The new compounds produced according to the invention have a central stimulating effect and suppress the appetite.
example 1
15 parts of 1- (p-chlorophenyl) -2-methyl-2-oxyethylamino-propane are dissolved in 100 parts of chloroform, the solution is saturated with hydrochloric acid and heated to reflux. Then 12 parts of tin chloride are added dropwise and the mixture is boiled for one hour. Then the
Evaporated dry and the residue from isopropanol with charcoal recrystallized. 12 parts of 1- (p-chlorophenyl) -2-methyl-chloroethylamino-propane are obtained as
Hydrochloride. The melting point is 179-1800 C.
Example 2
If 16 parts of 1-phenyl-2-methyl-2-oxyethylamino-propane are reacted in 100 parts of chloroform with gaseous hydrochloric acid and with 15 parts of thionyl chloride in the same way as described in Example 1, 12 parts of 1-phenyl are obtained -2-methyl-2-chloroethylaminopropane hydrochloride with a melting point of 180 181 "C.
Example 3
When using 1- (p-methoxyphenyl) -2-meth yl-2-oxyethylaminopropane and the same procedure as in Example 1, 1- (p-methoxyphenyl) -2 methyl-2-chloroethylamino-propane hydrochloride is used the melting point 198-199 ° C obtained.
Example 4
When using 1-benzyl-1-oxyethylamino-cyclohexane, analogously to Example 1, 1-benzyl-1-chloroethylamino-cyclohexane with a melting point of 205-2060 ° C. is obtained.
