Procedure

A mixture of the above ester (2.1 g, 4.5 mmol) and 20% sodium hydroxide (3.0 ml) in ethanol (21 ml) was stirred at room temperature for 16 h. The solution was poured into dichloromethane (250 ml) and acidified with 2 N hydrochloric acid. The organic phase was washed with water (10 ml), dried (MgSO4) and the solvent evaporated in vacuo. The foamy residue was stripped with acetone and crystallized from acetone, affording 1.5 g (70%) of the title compound.
