Procedure

At room temperature, 6.0 g of N-[2,6-dimethyl-4-{1-hydroxy-2,2,2-trifluoro-1-(trifluoromethyl)ethyl}phenyl] 3-aminobenzamide, 2.5 g of benzoyl chloride and 1.8 g of pyridine were introduced to 50 ml of tetrahydrofuran. After the loss of the starting material was confirmed through TLC, the reaction solution was filtered, and thus obtained filtrate was concentrated under reduce pressure. Thus obtained residue was purified by silica gel chromatography (eluent:hexane:ethyl acetate=3:1) to give 6.3 g (yield 85%) of the title compound as a powder form.
