Procedure

Prepared by the method described for Ex. 17 from 4-ethyl-1,5-dihydro-1,5-dioxo-4H-1-benzopyrano[3,4-b]pyridine-2-carboxylic acid (2.2 g, 0.0077 mole), 1,1'-carbonyldiimidazole (2.4 g, 0.0148 mole) and 5-aminotetrazole monohydrate (0.76 g, 0.0076 mole) in dimethylformamide (30 ml). Recrystallization from dimethylformamide gives pale yellow crystals (1.5 g, 55%), m.p. above 300.
