Reaction Steps

To a solution of 4-[6-(2-benzyloxycarbonylaminoethyloxy)-3-cyanoindol-1-yl]-2-hydroxybenzoic acid (0.087 g) in a mixed solvent ethyl acetate (2 mL) and methanol (2 mL) was added palladium-carbon powder (0.016 g) under an 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. This obtained light yellow solid was washed with diethyl ether, dried to give the title compound (0.058 g).
