Participants

Reaction Steps

5,6,7-Trichloro-2-(trifluoromethyl)-4-benzimidazolesulphonyl chloride (22 parts) in dry acetone (80 parts) was added dropwise to a solution of diethylamine (12 parts) in dry acetone (16 parts). The temperature was kept below 30° and the reaction mixture stirred for 2 hours. The solvent was evaporated and the residue treated with 6N hydrochloric acid. The solid product was collected, washed with water and dried (23 parts). Recrystallisation from toluene (charcoal) gave the required product as pale coloured needles (21.6 parts; m.p.[melting point] 152°-154°; 89.7%).
