Description
Verfahren zur Herstellung eines neuen Hydrazin-Derivates
Es wurde gefunden, dass man zum bisher unbekannten N- [2'-Oxo-5'-methyloxazolidinyl- (3')]-3- sulfamyl-4-chlor-benzoesäureamid der Formel I
EMI1.1
gelangt, indem man 3-Sulfamyl-4-chlor-benzoylchlorid mit 3-Amino-5-methyl-oxazolidon- (2) umsetzt.
Beispiel
N- [2'-Oxo-5'-methyl-oxazolidinyl- (3')]-
3-sulfamyl-4-chlor-benzoesäureamid
Eine Lösung von 3,5 g 3-Amino-5-methyl-oxa- zolidon- (2) und 3,0 g Triäthylarmin in 150 cm3 Chloroform wird unter Rühren bei 20-25 innert 30 Minuten mit 7,6 g 3-Sulfamyl-4-chlor-benzoyl- chlorid versetzt. Darauf wird die Reaktionslösung während 60 Stunden bei Zimmertemperatur weitergerührt, wobei sich eine schmierige Masse ausschei- det. Man dampft im Vakuum zur Trockne ein, versetzt den Eindampfrückstand mit 300 cm8 Essigsäureäthylester und 150 cm Wasser und schüttelt gut durch.
Nach Trennung der Schichten wird die Essigsäureäthylesterlösung mit total 150 cm3 Wasser gewaschen und über Magnesiumsulfat getrocknet.
Das Lösungsmittel wird im Vakuum abgedampft und der Rückstand über Aluminiumoxyd chromatogra- phiert wobei das N- [2'-Oxo-5'-methyl-oxazolidinyl- (3]-3-sulfamyl-4-chlorbenzoesäureamid mit einem Lösungsmittelgemisch von Essigsaureäthylester/ Methanol (9 : 1) eluiert wird. Nach Umkristallisieren aus Chloroform/Methanol (9 : 1) schmilzt das Sulfon- amid-Derivat bei 215-216 .

Process for the preparation of a new hydrazine derivative
It has been found that the previously unknown N- [2'-oxo-5'-methyloxazolidinyl- (3 ')] -3-sulfamyl-4-chloro-benzoic acid amide of the formula I
EMI1.1
obtained by reacting 3-sulfamyl-4-chlorobenzoyl chloride with 3-amino-5-methyl-oxazolidone- (2).
example
N- [2'-Oxo-5'-methyl-oxazolidinyl- (3 ')] -
3-sulfamyl-4-chloro-benzoic acid amide
A solution of 3.5 g of 3-amino-5-methyl-oxazolidone- (2) and 3.0 g of triethyl amine in 150 cm3 of chloroform is mixed with 7.6 g of 3-sulfamyl within 30 minutes while stirring at 20-25 -4-chloro-benzoyl chloride added. The reaction solution is then stirred for a further 60 hours at room temperature, a greasy mass separating out. It is evaporated to dryness in vacuo, the residue from evaporation is mixed with 300 cm8 of ethyl acetate and 150 cm of water and shaken well.
After separating the layers, the ethyl acetate solution is washed with a total of 150 cm3 of water and dried over magnesium sulfate.
The solvent is evaporated off in vacuo and the residue is chromatographed over aluminum oxide, the N- [2'-oxo-5'-methyl-oxazolidinyl- (3] -3-sulfamyl-4-chlorobenzoic acid amide) with a solvent mixture of ethyl acetate / methanol ( 9: 1) After recrystallization from chloroform / methanol (9: 1) the sulfonamide derivative melts at 215-216.
PATENT CLAIM
Process for the preparation of the previously unknown N-12'-oxo-5'-methyl-oxazolidinyl- (3 ')] -3-sulfamyl-4-chlorobenzoic acid amide of the formula I.
EMI1.2
characterized in that 3-sulfamyl-4-chlorobenzoyl chloride is reacted with 3-amino-5-methyl-oxazolidone- (2).
