Procedure
To a mixture of the compound (240 mg) prepared in Example 12, 1,2-dimethoxyethane (5.0 mL), and methanol (5.0 mL), 1N sodium hydroxide solution (3.0 mL) was added, and the mixture was stirred for 1 hour at room temperature. Methyl tert-butylmethyl ether was added to the reaction mixture, which was extracted by 1N sodium hydroxide solution. The water layer was neutralized by adding 5N hydrochloric acid and was extracted with ethyl acetate. The organic layer was washed with water and saturated brine solution, and was dried by anhydrous magnesium sulphate. The title compound (208 mg) having the following physical data was obtained by allowing the residue obtained by removing the solvent to recrystallize from a mixed solvent of n-hexane, ethyl acetate, and tetrahydrofuran.
