Procedure
The compound (6.02 g, 19.8 mmol) obtained in step F was dissolved in a methanol-tetrahydrofuran=1:1 mixed solvent (100 ml). 1N sodium hydroxide (100 ml) was added with stirring at room temperature, and the mixture was stirred at the same temperature for 2 hr. The reaction mixture was concentrated under reduced pressure, 1N hydrochloric acid (110 ml) was added, and the aqueous layer was extracted 4 times with chloroform. The organic layer was mixed, and dried over anhydrous magnesium sulfate. The insoluble material was filtered off, and the solution was concentrated under reduced pressure, and the obtained solid was washed with diethyl ether-hexane mixed solvent, and dried under reduced pressure to give the title compound (4.26 g, yield 87%) as a colorless solid.
