Methylene chloride was added to the reaction mixture and the resulting mixture was poured into 2 N aqueous sodium hydroxide solution and extracted with methylene chloride-methanol (10:1). The organic layer was dried over anhydrous sodium sulfate, the mixture was filtrated, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by medium pressure silica gel column chromatography (methylene chloride:methanol=49:1 to 32:1) to give the title compound (103.4 mg, 75%) as a pale yellow solid.
