Procedure

A solution of 5-chloro-4-methyl-1,2-phenylenediamine (7.8 g) in a mixture of formic acid (35 mL) and hydrochloric acid (300 mL) was heated at 50° C. for 3 hours then treated with ammonium hydroxide solution until the solution was basic. The reaction mixture was then extracted with dichloromethane. The extracts were evaporated to give 6-chloro-5-methyl-1H-benzoimidazole (7 g).
