Procedure

A mixture of N-[2-(benzylthio)-3,3-dimethoxypropyl]-4-methyl-7-[methyl(2-thienylsulfonyl)amino]-1H-indole-2-carboxamide (4.75 g), Amberlyst (registered trade mark) 15 ion exchange resin (1.0 g), acetone (100 mL) and water (0.4 mL) was stirred at room temperature for 20 hr. Amberlyst (registered trade mark) 15 ion exchange resin was filtered off, and washed with ethyl acetate. The filtrate was concentrated under reduced pressure, and the obtained residue was subjected to silica gel column chromatography (ethyl acetate:hexane=2:3-3:2) to give the title compound (4.4 g, yield: 100%) as a colorless amorphous solid. MS: 528 (MH+).
