Abstract

1509035 Substituted benzanilides PRODUITS CHIMIQUES UGINE KUHLMANN 23 July 1975 [24 July 1974] 30730/75 Heading C2C [Also in Division C4] N - Methyl - 4,4<SP>1</SP> - dinitrobenzanilide is prepared by condensing 4-nitrobenzoyl chloride with 4 - nitro - N - methyl - aniline or by nitrating N-(4-nitrobenzoyl)-N-methylaniline, and is subsequently reduced to N,-(4-aminobenzoyl) - N, - methyl - 1,4 - diaminobenzene. The corresponding N-ethyl and N 1 -ethyl homologues are prepared similarly.
