Procedure

To a suspension of lithium aluminum hydride (0.015 g) in tetrahydrofuran (2 ml) was added dropwise a solution of N-[2-(5-cyano-4,5-dihydro-1,3-thiazol-2-yl)-1H-indol-7-yl]-N-methylthiophene-2-sulfonamide (0.080 g) in tetrahydrofuran (3 ml) under ice-cooling, and the reaction mixture was stirred at 0° C. for 2 hr. 1N Aqueous sodium hydroxide solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (ethyl acetate:hexane=80:20-100:0), and recrystallized from hexane-ethyl acetate to give the title compound (0.029 g, yield 36%) as colorless crystals.
