A mixture of 4-[4-nitro-2-(trifluoromethyl)phenyl]morpholine (compound of Reference Example 2; 1.20 g, 4.344 mmol), platinum(IV) oxide (0.10 g) and methanol (12 ml) was stirred at room temperature for 12.5 hours under hydrogen atmosphere. The reaction mixture was filtered and the residue obtained by evaporation of the solvent of the filtrate under reduced pressure was washed with n-hexane to give the title compound (0.62 g, 58%) as a colorless crystal.
