Reaction Steps
3Methoxy-2-quinoxalinecarboxylic acid (1.5 g) and N,N-carbonyldiimidazole (1.2 g) in tetrahydrofuran (50 ml) were heated under reflux for 15 minutes. 5-Amino-1H-tetrazole (0.7 g) in dimethylformamide (5 ml) was added and the solution was heated under reflux for 1 hour. The crystalline solid was collected and stirred with dilute hydrochloric acid (25 ml., 2N) and the solid was filtered off and dried. It had m.p. 260° (d) (45%).
