Procedure

A mixture of 4-chloro-N-methyl-2-nitro-5-(4-trifluoromethyl-piperidin-1-yl)aniline (1.07 g, 3.2 mmol), THF (20 mL), MeOH (30 mL) and Pt/C (100 mg) was stirred for 6 h at rt under a hydrogen atmosphere (3 bar). The catalyst was removed by filtration and the mixture was concentrated to give the sub-title compound.
