Procedure

A total of 652 mg of {4-fluoro-3-(3-fluoro-phenyl)-1-trityl-1H-indazol-5-yl}-carbamic acid benzyl ester obtained in Production Example II-19-b was dissolved in 20 ml of methanol, 652 mg of 10% palladium-carbon, and the mixture was subjected to catalytic hydrogenation at room temperature at normal pressure. After stirring for 4 hours, the mixture was filtered through Celite, and the filtrate was evaporated. The residue was purified and separated by silica gel column chromatography (ethyl acetate:hexane=1:5), to give 297 mg of the title compound.
