Procedure

A mixture of N-(2-methyl-3-nitro-phenyl)-methanesulfonamide (1.5 g) and tin(II) chloride dihydrate (7.4 g) in ethanol (15 mL) and ethyl acetate (15 mL, from Burdick and Jackson, Muskegon, Mich.) was stirred at room temperature overnight. The reaction mixture was treated with saturated sodium bicarbonate solution to pH>9. The mixture was filtered and the filtrate was washed with water and brine. After drying over anhydrous sodium sulfate and evaporation of solvent, N-(3-amino-2-methyl-phenyl)-methanesulfonamide (1 g) was obtained.
