Procedure
To a mixture of 7-[methyl(2-thienylsulfonyl)amino]-1H-indole-2-carboxylic acid (1.00 g), 1H-1,2,3-benzotriazol-1-ol (0.48 g) and N,N-dimethylformamide (10 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (0.68 g) at room temperature. The mixture was stirred at 50° C. for 30 min, and hydrazine monohydrate (0.74 g) was added. The reaction mixture was stirred at room temperature for 1 hr, and water was added. The resulting crystals were filtrated, washed with water, and dried to give the title compound (0.88 g, yield 84%) as colorless crystals. melting point 273-274° C. (decomposition).
