실험 절차

0.53 g of 3-chloro-2-pyridinecarboxylic acid, 10 ml of thionyl chloride and 0.27 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 ethanol, whereby 0.28 g of N-(5-tetrazolyl)-3-chloro-2-pyridinecarboxamide is obtained.
