Reaction Steps
The cyanoxanthone from step (B) (2.9 g), sodium azide (0.61 g), ammonium chloride (0.53 g) and dimethylformamide (50 ml) were heated together at 125° for 8 h. The reaction mixture was poured into an iced aqueous solution of hydrochloric acid (excess) and the product filtered off and dried. Recrystallisation from dimethylformamide yielded the title compound, m.p. 216°-218° C.
