Procedure
41.6 ml of aqueous 30% hydrogen peroxide was added dropwise at 40° C. over a period of 20 minutes to a solution of 26.2 g of Intermediate XXI in 300 ml of glacial acetic acid. The mixture was heated to 60° C., stirred at that temperature for 4.5 hours, cooled to ambient temperature and poured into 60 ml of water. Filtration on a Buchner funnel gave a filter cake which was washed with water and desiccated, yielding 29.4 g of the title compound. A sample was crystallized from ethanol. m.p. (89) 159°-161° C.
