Procedure

A mixture of 5-(2-methoxyethoxy)-7-[methyl(pyridin-2-ylsulfonyl)amino]-1H-indole-2-carboxylic acid (1.60 g), 1-[4-(benzylthio)tetrahydro-2H-thiopyran-4-yl]methanamine (1.00 g), 1H-1,2,3-benzotriazol-1-ol (0.90 g), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (1.12 g) and N,N-dimethylformamide (20 mL) was stirred at room temperature for 15 hr. The reaction mixture was concentrated, water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with 1N hydrochloric acid, saturated aqueous sodium hydrogencarbonate solution and saturated brine, dried (MgSO4), and concentrated. The obtained residue was subjected to silica gel column chromatography, and eluted with hexane-ethyl acetate (4:1-1:1, volume ratio) to give the title compound (1.92 g, yield 77%) as a colorless amorphous solid.
