반응 단계
To a solution of ethyl {4-[(2-{7-[(2-thienylsulfonyl)amino]-1H-indol-2-yl}-1,3-thiazol-5-yl)methyl]piperazin-1-yl}acetate (0.500 g) in a mixed solvent of tetrahydrofuran (15 ml) and methanol (5 ml) was added 2N aqueous sodium hydroxide solution (1.5 ml), and the mixture was stirred at 50° C. for 2 hr. 10% Aqueous citric acid solution, ethyl acetate, sodium chloride and tetrahydrofuran were successively added to the reaction solution, and the precipitated crystals were collected by filtration, washed with ethyl acetate, and dried to give the title compound (0.360 g, yield 76%) as colorless crystals.
