Description
Verfahren zur Herstellung eines Salzes des Ni-(3,4-Dimethylbenzoyl)- p-aminobenzolsulfonamids. Lösungen von Salzen der p-Aminobenzol- sulfonamide werden, sofern sie nicht stark alkalisch reagieren, vielfach für Injektionen verwendet. Für diesen Zweck ist es jedoch von Wichtigkeit, dass die Lösungen möglichst neutral reagieren, da sonst die Gefahr der Nekrosebildung besteht.
Es wurde nun ge funden, dass die Salze des N,-(3,4-Dimethyl- benzoyl)-p-aminobenzolsulfonamids viel weni ger alkalisch reagieren als die vergleichbaren Salze bekannter p-Aminobenzolsulfonamide;
beispielsweise zeigt das Natriumsalz des Na.- (3,4 -Dimethylbenzoyl) -p-aminobenzolsulfon- amids in 5 %iger wässriger Lösung einen pu von 7,6, während die Natriumsalze des 2-(p- Aminobenzolsulfamido) - pyridins 11,2, des p-Aminobenzolsulfamido-2-thiazols 10,
0 und des 2-Sulfanilamidopyrimidins einen pn von 9,6 bis 9,7 (je in 2 % iger Lösung) aufweisen.
Als Basen kommen für die Herstellung der Salze des Ni (3,4.-Dimethylbenzoyl)-p- aminobenzolsulfonamids die üblichen Alka- lien in Frage, zum Beispiel Natronlauge, Ma gnesiumhydroxyd, Erdalkalihydroxyde oder auch organische Basen wie zum Beispiel Di- äthylamin, Morpholin, Aminoäthanol etc.
Gegenstand vorliegenden Patentes ist ein Verfahren zur Darstellung eines Salzes des Nl- (3,4-Dimethylbenzoyl)-p-aminobenzolsul- fonamids, welches dadurch gekennzeichnet ist, dass man Nl-(3,4-Dimethylbenzoyl)-p- aminobenzolsulfonamid durch Einwirkenlas sen einer alkalisch reagierenden Natriumver- bindung in sein Natriumsalz überführt.
Das Salz stellt ein. kristallisiertes, leicht wasser lösliches Pulver dar, welches therapeutische Verwendung finden soll. <I>Beispiel:</I> 50 Teile<B>Ni-</B> (3,4-Dimethylbenzoyl)-sulfanil- amid werden in 200 Volumteilen doppelt de stilliertem Wasser suspendiert und mit einer verdünnten Lösung von reiner Natronlauge in doppelt destilliertem Wasser langsam ver- setzt, bis fast alles in Lösung gegangen ist. (Reaktion auf Phenolphthalein neutral, auf Lackmus schwach alkalisch). Nun wird noch einige Zeit auf 10" abgekühlt und dann fil triert.
Das Filtrat wird nochmals durch eine Schicht Tierkohle filtriert und dann im Va kuum eingedampft. Eine ungefähr 5 ' ige Lösung kann auch mit gesättigter Kochsalz lösung versetzt werden, wobei das Natrium salz schön kristallisiert. ausfällt.
Process for the preparation of a salt of Ni (3,4-dimethylbenzoyl) - p-aminobenzenesulfonamide. Solutions of salts of the p-aminobenzenesulfonamides are often used for injections, provided they do not have a strong alkaline reaction. For this purpose, however, it is important that the solutions react as neutrally as possible, otherwise there is a risk of necrosis.
It has now been found that the salts of N, - (3,4-dimethylbenzoyl) -p-aminobenzenesulfonamide are much less alkaline than the comparable salts of known p-aminobenzenesulfonamides;
for example, the sodium salt of Na.- (3,4-dimethylbenzoyl) -p-aminobenzenesulfonamide in 5% aqueous solution has a pu of 7.6, while the sodium salts of 2- (p-aminobenzenesulfamido) pyridine 11.2 , des p-aminobenzenesulfamido-2-thiazole 10,
0 and 2-sulfanilamidopyrimidine have a pn of 9.6 to 9.7 (each in 2% solution).
Suitable bases for the preparation of the salts of Ni (3,4-dimethylbenzoyl) -p-aminobenzenesulfonamide are the usual alkali, for example sodium hydroxide, magnesium hydroxide, alkaline earth hydroxide or organic bases such as diethylamine, morpholine , Aminoethanol etc.
The subject of the present patent is a process for the preparation of a salt of Nl- (3,4-dimethylbenzoyl) -p-aminobenzenesulfonamide, which is characterized in that Nl- (3,4-dimethylbenzoyl) -p-aminobenzenesulfonamide is allowed to act an alkaline sodium compound converted into its sodium salt.
The salt sets. crystallized, easily water-soluble powder, which is intended to find therapeutic use. <I> Example: </I> 50 parts of <B> Ni </B> (3,4-dimethylbenzoyl) -sulfanil- amide are suspended in 200 parts by volume of double-distilled water and in double with a dilute solution of pure sodium hydroxide solution distilled water slowly added until almost everything has gone into solution. (Reaction to phenolphthalein neutral, to litmus weakly alkaline). Now it is cooled down to 10 "for some time and then filtered.
The filtrate is filtered again through a layer of animal charcoal and then evaporated in a vacuum. A solution of approximately 5 'can also be mixed with saturated common salt solution, whereby the sodium salt crystallizes nicely. fails.
