Procedure
A solution of 5-amino-1,2,3,4-tetrazole (0.425 g.) in dry pyridine (10 ml.) was added to 6-ethylcinnolin-3-yl carbonyl chloride (1.1 g.). The resulting solution was kept at room temperature overnight, and water (50 ml.) and N-hydrochloric acid (50 ml.) were then added. The mixture was filtered, and the solid residue washed with water and crystallised from aqueous dimethylformamide to give 6-ethyl-N-(1,2,3,4-tetrazol-5-yl)cinnolin-3-yl carboxamide, m.p. over 250° C.
