Abstract

1,241,587. Benzimidazoles. ILFORD Ltd. 10 Feb., 1970 [14 Nov., 1968], No. 54160/68. Heading C2C. [Also in Divisions C4 and G2-G3] 1 . Ethyl - 2 - methyl - 5 - trifluoromethyl- 6-cyanobenzimidazole is prepared by diazotizing the corresponding 6-amino compound and reacting the product with CuCN/NaCN. The benzimidazole is then quaternized to form the corresponding 3-(sulphobutyl) and 3-ethyl benzimidazolium salts.
