Procedure

0.48 g of 4-nitro-2-pyridinecarboxylic acid, 0.48 g of N,N'-carbonyldiimidazole and 0.27 g of 5-aminotetrazole are treated in the same manner as described in Example 2. The crude product thus obtained is recrystallized from ethanol, whereby 0.38 g of N-(5-tetrazolyl)-4-nitro-2-pyridinecarboxamide is obtained.
