Procedure

A mixture of N-[2-(benzylthio)-3,3-dimethoxypropyl]-5-(2-methoxyethoxy)-7-[(pyridin-2-ylsulfonyl)amino]-1H-indole-2-carboxamide (3.0 g), Amberlyst (registered trade mark) 15 ion exchange resin (600 mg), acetone (80 mL) and water (260 mg) was stirred at room temperature for 15 hr. The insoluble substance was removed by filtration, and the filtrate was concentrated. The residue was subjected to silica gel column chromatography, and eluted with hexane-ethyl acetate (2:3-1:9, volume ratio) to give the title compound (2.09 g, yield 75%) as colorless crystals.
