To a solution of 3,6 g (18 mM) of N-(2,2-difluoroethyl)-2-nitroaniline in 25 ml of methanol, were added 470 mg of palladium on carbon at 5%. The reaction mixture was stirred for 3 h at room temperature under hydrogen atmosphere, at room pressure and room temperature. The catalyst was filtrated on Celite and the filtrate was evaporated under vacuum to give 3 g of N-(2,2-difluoro ethyl)benzene-1,2-diamine as an oil. Yield: 97,5%.
