Procedure

To a mixture of N-[2-(benzylthio)-2-methyl-3-oxopropyl]-5-(2-methoxyethoxy)-7-[methyl(pyridin-2-ylsulfonyl)amino]-1H-indole-2-carboxamide (1.56 g) and 1,2-dichloroethane (50 mL) was added thiomorpholine (1.31 mL) at room temperature, and the mixture was stirred at room temperature for 30 min. Sodium triacetoxyborohydride (1.66 g) was added, and the reaction mixture was stirred overnight at room temperature. Aqueous sodium bicarbonate was added, and the mixture was extracted with 1,2-dichloroethane. The extract was washed with saturated brine, dried over sodium sulfate, and filtrated, and the filtrate was concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography to give the title compound (998 mg, yield 56%) as a colorless amorphous solid from a fraction eluted with ethyl acetate-hexane (9:1).
