Procedure

Compound 10 (160 mg, 0.38 mmol) was stirred in acetone (7 mL) and water (2 mL) at 63° C. in the presence of p-TsOH (5 mg, cat. amount) for 2 h. After cooled to room temperature, water was added and the reaction mixture was extracted with EtOAc. Combined organic layers were washed with water and brine and dried over Na2SO4. Purification of the concentrated crude product by column chromatography (EtOAc:Hexane=1:1) afforded the title product as a white solid (100 mg, 69%).
