Reaction Steps
Trifluoroacetic acid (0.8 ml) was added to dry 2,6-lutidine (10 ml) and the mixture was then treated with 3-cyano-5-methylsalicylic acid (0.885 g), sodium azide (0.65 g) and lithium chloride (20 mg), and heated at reflux for 20 hours. The mixture was then diluted with water (20 ml) and acidified by treatment with concentrated hydrochloric acid. The resulting precipitate was collected and recrystallized from a large amount of acetic acid to give 5-methyl-3-(tetrazol-5-yl)salicylic acid (0.65 g), m.p. 290°-292° C. (with decomposition).
