Procedure
0.25 g (0.54 mmol) of the ester from Example 81 were stirred at room temperature overnight with 5 ml ethanol and 0.7 ml 2 N aqueous sodium hydroxide. The mixture was brought to pH 4 with 2 N acetic acid, and the precipitate of the acid (338) was filtered with suction, washed successively with water and with acetone, and dried in vacuo. Yield: 0.16 g (74%) of a pale yellow powder, m.p. 241-242° C. (dec.).
