Procedure

16 g of the product of Step B is dissolved in a minimum amount of ethanol and the solution added to 96 ml of 20% aqueous sodium hydroxide. Under a nitrogen atmosphere, the mixture is heated to 110° for 6 hours while permitting most of the ethanol to distill off. After cooling, the mixture is acidified to PH2 with conc. hydrochloric acid, the title product recovered by filtration, and refined by crystallization from petroleum ether, m.p. 64° - 67°.
