Procedure
In the same manner as described in Example 1-(1), 4-methoxy-6-(3-nitrophenyl)-2-pyridinecarboxylic acid (0.4 g), carbonyldiimidazole (0.22 g) and 5-aminotetrazole (0.15 g) are reacted to give N-(5-tetrazolyl)-4-methoxy-6-(3-nitrophenyl)-2-pyridinecarboxamide (0.31 g). M.P. 269°-272.5° C. (decomp.) (wetted from about 250° C.) (recrystallized from dimethylformamide-ethyl acetate)
