Procedure
The compound of Example 74-1 (33 mg, 0.06 mmol) was dissolved in methanol (1 ml) and THF (1 ml) and thereto was added 2N aqueous lithium hydroxide solution (1 ml), followed by stirring under reflux for 8 hours. The mixture was diluted with water and washed with ethyl ether. The aqueous layer was adjusted to around pH 4 with 5% aqueous potassium hydrogen sulfate solution and the solution was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate and filtered. The solvent was removed in vacuo to give the subject compound (28 mg, 96%).
