Procedure
1.45 g of 3-methoxy-2-pyridinecarboxylic acid, 30 ml of thionyl chloride and 0.95 g of 5-aminotetrazole are treated in the same manner as described in Example 1. The crude product thus obtained is recrystallized from a mixture of dimethylformamide and water, whereby 0.18 g of N-(5-tetrazolyl)-3-methoxy-2-pyridinecarboxamide is obtained.
