실험 절차

To a solution of the compound obtained in Example 29 (4) (0.0306 g) in 1,4-dioxane (0.5 ml), 10% lithium hydroxide aqueous solution (0.5 ml) was added at −5° C. under argon atmosphere and the mixture was stirred for 2 hours. To the reaction solution was then added 10% hydrochloric acid and the mixture was extracted with chloroform. The organic layer was washed with a saturated aqueous NaCl solution, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure to obtain 0.0285 g of the desired product as a white powder.
