Procedure

A mixture of 5-(2-methoxyethoxy)-7-{methyl[(1-methyl-1H-imidazol-2-yl)sulfonyl]amino}-1H-indole-2-carboxylic acid (2.3 g), 2-(benzylthio)-3,3-dimethoxypropan-1-amine (1.7 g), 1H-1,2,3-benzotriazol-1-ol (1.2 g), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (1.6 g) and N,N-dimethylformamide (70 mL) was stirred at room temperature for 14 hr. The reaction solution was concentrated under reduced pressure, ethyl acetate and water were added, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with water, aqueous citric acid solution, saturated aqueous sodium hydrogencarbonate solution and saturated brine, dried over magnesium sulfate, and filtrated, and the filtrate was concentrated under reduced pressure. The obtained crude product was subjected to silica gel column chromatography (ethyl acetate:hexane=20:80-80:20) to give the title compound (3.2 g, yield 89%) as a colorless oil.
