Reaction Conditions

Reaction Steps

A mixture of ethyl [(2-{7-[methyl(2-thienylsulfonyl)amino]-1H-indol-2-yl}-1,3-thiazol-5-yl)methoxy]acetate (0.08 g), 1N aqueous sodium hydroxide solution (0.30 mL), tetrahydrofuran (4 mL) and methanol (4 mL) was stirred at 60° C. for 1 hr. The reaction mixture was concentrated, and water was added to the residue. The mixture was acidified with 10% aqueous citric acid solution, and the resulting crystals were filtrated, washed with water, and dried to give the title compound (0.04 g, yield 45%) as pale-yellow crystals. melting point 197-198° C.
