Procedure

2.52 g (6.44 mmol) of the ester obtained in Example 8, in solution in 30 ml of methanol, were treated with 2.5 g of sodium hydroxide and heated at reflux for 3 hours. After the same treatment as in Example 7, followed by recrystallization from hexane, 2.35 g (97%) of the expected coompound, melting at 262°-264° C., are isolated.
