Procedure

A mixture of the above ester (0.99 g, 2 mmol) and 20% sodium hydroxide (1.5 ml) in ethanol (13 ml) was stirred at room temperature for 4 h. The mixture was poured into dichloromethane (100 ml), acidified with 2 N hydrochloric acid and washed with water (10 ml). The organic solution was dried (MgSO4) and activated charcoal was added. The mixture was stirred for 10 minutes, filtered and the solvent was removed in vacuo. The residue was triturated with acetone and the solid product was overlaid with ethyl acetate, stirred for 15 minutes, filtered off and washed with ethyl acetate. After drying, the title compound (0.80 g, 74%) was obtained.
