Procedure

A solution of 8.0 g of N-[2,6-dimethyl-4-{1-hydroxy-2,2,2-trifluoro-1-(trifluoromethyl)ethyl}phenyl]3-nitrobenzamide and 0.8 g of 10% palladium carbon added to 50 ml of methanol was stirred in a hydrogen atmosphere at room temperature. After disappearance of the starting raw material was confirmed by means of TLC, the reaction solution was filtered and the obtained filtrate was concentrated under a reduced pressure. The resulting residue was purified by silica gel column chromatography using an eluent (development solvent; hexane:ethyl acetate=3:1) to obtain 6.3 g of the desired product (Yield: 85%) in the form of powder.
