실험 절차

A mixture of ethyl 4-methyl-2-{7-[(2-thienylsulfonyl)amino]-1H-indol-2-yl}-1,3-thiazole-5-carboxylate (0.42 g), 8N aqueous sodium hydroxide solution (0.4 mL), tetrahydrofuran (6 mL) and methanol (6 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. The obtained crystals were dissolved in tetrahydrofuran, treated with activated carbon, and concentrated to give the title compound (0.17 g, yield 44%) as yellow crystals. The crystals were recrystallized from ethyl acetate-hexane. melting point>253° C. (decomposition).
