Abstract
1475259 Aminophenyl chloroformate hydrochlorides SOC NATIONALE DES POUDRES ET EXPLOSIFS 2 Dec 1975 [17 Dec 1974] 49459/75 Heading C2C The invention relates to (a) the preparation of N,N-dialkylaminophenyl chloroformate hydrochlorides by reacting an N,N-dialkylaminophenol with COCl 2 , the reaction being carried out in solution in a chlorinated aliphatic hydrocarbon below 0‹ C.; and (b) 3- or 4-(N,N-di- (C 1 -C 5 alkyl)amino)phenyl chloroformate hydrochlorides per se which may be obtained by the method (a). A specified solvent is dichloromethane. N<SP>1</SP>N<SP>1</SP> - Dialkylaminophenyl N - alkylcarbamates are obtained by reacting the N,N-dialkylaminophenyl chloroformate hydrochlorides obtained as above with primary alkylamines.
