실험 절차

A mixture of ethyl 3-(2-{7-[methyl(2-thienylsulfonyl)amino]-1H-indol-2-yl}-1,3-thiazol-5-yl)propanate (3.58 g), 2N aqueous sodium hydroxide solution (10.0 mL), tetrahydrofuran (10 mL) and methanol (10 mL) was stirred at 60° C. for 1 hr. The reaction mixture was concentrated, and water was added to the residue. The mixture was acidified with 10% aqueous citric acid solution, and the resulting crystals were filtrated, washed with water, and dried to give the title compound (3.34 g, yield 99%) as pale-yellow crystals. melting point 234-235° C.
