Procedure

To a solution of N-{2-[5-(morpholinomethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-(2-thienylsulfonyl)glycine ethyl ester (120 mg) in tetrahydrofuran (3 mL) and methanol (3 mL) was added, under ice-cooling, a solution prepared by dissolving potassium hydroxide (purity 85%, 30 mg) in water (1 mL), and the mixture was stirred for 30 min, and then at room temperature for 1 hr. 1M Hydrochloric acid was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4), and concentrated. The residue was recrystallized from a mixed solvent of ethyl acetate-hexane to give the title compound (106 mg, yield 93%) as white crystals. MS: 521 (MH+).
