Versuchsvorschrift

To a solution of compound (20)(2.77 g, 20.0 mmol) in methanol (5 ml) was added a 28% sodium methylate-methanol solution (5.0 g, 24.0 mmol) at room temperature and the mixture was stirred for one hr. The solvent was concentrated and the obtained residue was partitioned between ethyl acetate and iced-brine. The organic layer was dried over anhydrous magnesium sulfate and the solvent was evaporated under reduced pressure. The obtained residue was recrystallized from a small amount of isopropyl ether to give the title compound (2.3 g, 86%).
