To a mixture of ethyl(2-{5-(2-methoxyethoxy)-7-[methyl(2-thienylsulfonyl)amino]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)acetate (200 mg), tetrahydrofuran (5 mL) and methanol (1 mL) was added lithium borohydride (16 mg), and the mixture was stirred at room temperature for 1 hr. Lithium borohydride (16 mg) was added to the mixture, and the mixture was further stirred at room temperature for 1 hr. Lithium borohydride (16 mg) was added to the mixture, and the mixture was further stirred at room temperature for 1 hr. Water 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 subjected to silica gel column chromatography, and eluted with hexane-ethyl acetate (1:1-1:9, volume ratio) to give yellow crystals. The crystals were recrystallized from ethyl acetate-hexane to give the title compound (100 mg, yield 56%) as a pale-yellow powder. melting point 122-123° C.
