Reaction Steps

To a solution of 4-(6-benzyloxy-3-cyanoindol-1-yl)-2-methoxymethoxybenzoic acid ethyl ester in a mixed solvent of ethyl acetate (60 mL) and methanol (60 mL) was added palladium-carbon powder (0.61 g) under argon atmosphere at 0° C. and this mixture was stirred at 40° C. under a hydrogen atmosphere for 3 hours. The insoluble material was removed by filtration, and the filtrate was concentrated under reduced pressure to give the title compound (2.5 g)
