To a solution of the compound prepared in example 1 (204 mg) in dimethoxyethane (3 ml) and methanol (2 ml) was added 1N aqueous solution of sodium hydroxide. After stirred for 2 h, the mixture was quenched by addition of 1N hydrochloric acid. The mixture was extracted with ethyl acetate. The extract was washed with water and a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium salfate, and evaporated. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:4→ethyl acetate) to give the title compound (171 mg) having the following physical data.
