Procedure

To a solution of the compound (0.10 g, 0.25 mmol) of Example 101 in ethanol (4.0 mL), 50% potassium hydroxide solution (2.0 mL, 0.036 mol) was added at ambient temperature. The mixture was refluxed for 2 h. Cooled to ambient temperature, the solvent was removed under reduced pressure. Water was added to this residue, the mixture was washed with ethyl acetate then 1M hydrochloric acid was added to adjust pH to acidic, and then extracted with ethyl acetate. The organic layer was dried over sodium sulfate and concentrate then purified by chromatography on silica gel(dichloromethane/methanol) to afford the titled compound as solid (0.012 g, y. 14%).
