Procedure

To a mixture of 7-[(2-thienylsulfonyl)amino]-1H-indole-2-carboxylic acid (0.34 g), S-benzyl-N-propyl-L-cysteinamide (0.27 g), 1H-1,2,3-benzotriazol-1-ol (0.22 g) and N,N-dimethylformamide (15 ml) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (0.27 g) at 4° C., and the mixture was stirred at room temperature for 18 hr. The reaction solution was diluted with ethyl acetate, washed with water, aqueous sodium hydrogencarbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography (ethyl acetate:hexane=1:9-1:1), and the obtained crystals were washed with ethyl acetate-hexane to give the title compound (285 mg, yield 49%) as colorless crystals. melting point 124-125° C.
