Reaction Steps

6-Cyano-2-methoxyxanthone (12.6 g) was heated with sodium azide (3.41 g) and ammonium chloride (2.95 g) in dimethylformamide (100 ml) at 125° for 6 h. The reaction mixture was diluted with water and acidified with excess hydrochloric acid. The precipitated 2-methoxy-6-(5-tetrazolyl)xanthone was filtered off, washed with water, and recrystallised from dimethylformamide, decomposes above 300°.
