Procedure

A solution of the compound obtained in example 17 b) (5.6 g) and sodium hydroxide (5 g) in water (20 ml) was refluxed for 10 hours. After cooling, water (200 ml) was added and the mixture was adjusted to pH 2 by the addition of concentrated hydrochloric acid. The resulting precipitate from the mixture was collected by filtration, washed with water, dried to give the title compound (3.05 g, 76.4%) which was recrystallized from DMF-ethanol to white crystals, mp 300° C.
