Participants

Reaction Steps

To a mixture of 7-[(2-thienylsulfonyl)amino]-1H-indole-2-carboxylic acid (0.60 g), 1H-1,2,3-benzotriazol-1-ol (0.28 g) and N,N-dimethylformamide (6 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (0.40 g) at room temperature. The mixture was stirred for 10 min and hydrazine monohydrate (0.28 mL) was added. The reaction mixture was stirred at room temperature overnight, and water was added. The resulting crystals were filtrated, washed with water, and dried to give the title compound (0.28 g, yield 44%) as colorless crystals. melting point>276° C. (decomposition).
