Procedure

To a mixture of 7-[(2-methoxyethyl)(2-thienylsulfonyl)amino]-1H-indole-2-carboxylic acid (0.46 g), 2-(tritylthio)ethylamine hydrochloride (0.47 g), 1H-1,2,3-benzotriazol-1-ol (0.19 g), triethylamine (0.20 mL) and N,N-dimethylformamide (10 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (0.28 g) at 0° C., and the mixture was stirred at 50° C. for 1 hr. Water was added to the reaction mixture, and the obtained crystals were filtrated, washed with water and dried to give the title compound (0.90 g, quantitative) as colorless crystals. melting point 65-66° C.
