Procedure
The compound (6) (0.235 g, 0.645 mmol) was dissolved in 10 ml of THF/water (1:1) and a hydrate of lithium hydroxide (0.135 g, 3.23 mmol) was added thereto at a room temperature. The reaction mixture was stirred at 60° C. for 2 hours. After the reaction was completed, the pH of the reaction mixture was adjusted to 3˜4 and the reaction mixture was extracted with dichloromethane three times. An organic layer was dried with anhydrous magnesium sulfate and the solvent was removed under reduced pressure to quantitatively obtain the title compound in the form of a white crystal (7) (mp 238° C.).
