Procedure

0.3 g (0.66 mmol) of the ester from Example 75 were stirred overnight at room temperature with a mixture of 5 ml ethanol and 0.5 ml 2 N aqueous sodium hydroxide solution. It was brought to pH 5 with 2 N acetic acid. The precipitate of the title compound was filtered with suction, washed successively with water and with acetone, and dried in vacuo. Yield: 0.19 g (74%) of a white powder, m.p. 269-270° C.(dec.).
