Procedure

A total of 939 mg of (3-benzo[b]thiophen-2-yl-4-methoxy-1-trityl-1H-indazol-5-yl)-carbamic acid benzyl ester obtained in Production Example II-39-a was dissolved in 20 ml of a 2:1 solvent mixture of ethyl acetate and methanol. 300 mg of 20% palladium hydroxide-carbon was added thereto, and the mixture was subjected to catalytic hydrogenation at room temperature and at normal atmospheric pressure in the presence of. The reaction mixture was filtrated through Celite, and the solvent was removed, to give 458 mg of the title compound.
