Procedure

To a mixture of lithium aluminum hydride (0.05 g) and tetrahydrofuran (6 mL) was added N-[2-(5-cyano-5-methyl-4,5-dihydro-1,3-thiazol-2-yl)-1H-indol-7-yl]-N-methylthiophene-2-sulfonamide (0.40 g) at 0° C., and the mixture was stirred for 15 min. Ethanol (2 mL) and 1N aqueous sodium hydroxide solution (0.2 m) were successively added, and the resulting inorganic salt was removed by filtration. The filtrate was concentrated, and the residue was subjected to basic silica gel column chromatography to give the title compound (0.23 g, yield 57%) as colorless crystals from a fraction eluted with ethyl acetate. melting point 164-165° C.
