Reaction Steps
To a mixture of 7-[(2-thienylsulfonyl)amino]-1H-indole-2-carboxylic acid (1.00 g), 1-amino-2-methylpropan-2-ol (0.55 g), 1H-1,2,3-benzotriazol-1-ol (0.50 g) and N,N-dimethylformamide (15 mL) was added N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (0.71 g) at 0° C., and the mixture was stirred at 60° C. overnight. Water was added to the reaction mixture and the mixture was acidified with 10% aqueous citric acid solution. The resulting crystals were filtrated, washed with water, and dried to give the title compound (0.77 g, yield 65%) as colorless crystals. melting point>234° C. (decomposition).
