Reaction Steps

To a solution of 2-(p-aminophenyl)- 4-trifluoromethylimidazole (3.0 g.) in acetone (50 ml.) and triethylamine (2.7 g.) is added methanesulfonyl chloride (1.5 g.). After refluxing for 4 hours, a second portion of methanesulfonyl chloride (1.5 g.) is added. Reflux is continued 20 hours, a third portion of methanesulfonyl chloride (1.5 g.) is added and reflux continued another 4 hours. The reaction mixture is filtered and concentrated to an oil which, upon trituration with water, affords a solid. After chromatography on silica gel and recrystallization from a mixture of acetonitrile and water 1.3 g. of 2-(p-methylsulfonamidophenyl)-4-trifluoromethylimidazole, m.p. 253-255° C. is obtained.
