| titleOfInvention | Di(3-(2-chloroethylsulfonyl)-1-propyl)amine hydrochloride and a process for its preparation |
| abstract | Process for preparing di(3-(2-chloroethylsulfonyl)-1-propyl)amine hydrochloride, by n reacting 1 mol of an N,N-diallylcarboxamide of the formula (1) n n R-CON(CH.sub.2 --CH═CH.sub.2).sub.2 (1) n n in which R is hydrogen, alkyl(C 1 -C 6 ) or cycloalkyl(C 4 -C 8 ) with about 4 to about 8 mol of mercaptoethanol at temperatures of about 0° to about -70° C. in the presence of pure oxygen or a mixture of oxygen with an inert gas or an inert gas mixture, if appropriate in an inert organic solvent, to give the carboxamide of the formula (2) n n R--CON(CH.sub.2 --CH.sub.2 --CH.sub.2 --S--CH.sub.2 --CH.sub.2 n n --OH) 2 (2) n in which R has the abovementioned meaning, n hydrolyzing this compound with the aqueous solution of an alkaline agent at temperatures of about 40° to about 120° C. at a pH of about 10 to about 14, and n reacting 1 mol of the di(3-(2-hydroxyethylthio)-1-propyl)amine thus obtained with about 4 to about 6 mol of chlorine gas in about 2 to about 15% hydrochloric acid at temperatures of about 20° to about 110° C. to give di(3-(2-chloroethylsulfonyl)-1-propyl)amine hydrochloride. |
