実験手順

To a mixture of 7-{[(5-chloro-2-thienyl)sulfonyl]amino}-1H-indole-2-carboxylic acid (0.84 g), 2-(tritylthio)ethylamine hydrochloride (0.85 g), 1H-1,2,3-benzotriazol-1-ol (0.35 g), triethylamine (0.36 mL) and N,N-dimethylformamide (20 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (0.50 g) at 0° C., and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the obtained crystals were filtrated, washed with water and dried. The obtained crystals were subjected to silica gel column chromatography and the title compound (1.41 g, yield 97%) was obtained as colorless crystals from a fraction eluted with ethyl acetate. melting point>197° C. (decomposition).
