Abstract

1,191,638. Alkylsulphonylbenzimidazoles. GEVAERT-AGFA N.V. 14 Aug., 1967 [8 Sept., 1966], No. 40140/66. Heading C2C. [Also in Divisions C4, G2 and H1] Compounds of general formulµ are prepared by reacting the corresponding free base with ethyl iodide, propane, sultone or 4- bromo - N - acetyl butane sulphonamide respectively. 2 - Nitro - 4 - methyl sulphonyl - N - ethyl aniline is prepared by reacting ethylamine with 2-nitro-4-methyl sulphonyl chlorobenzene and reacted with acetic anhydride and hydrogenated to give 1-ethyl-2-methyl-5-methyl sulphonylbenzimidazole. 2 - Nitro - 4 - ethyl sulphonyl - N - methyl aniline, 1,2 - dimethyl - 5 - ethyl sulphonyl benzimidazole, 2- nitro - 4 - ethyl sulphonyl-N- ethyl aniline, and 1-ethyl-2-ethyl-5-ethyl sulphonyl benzimidazole are obtained similarly.
