Procedure

A mixture of 6-aminopyridine-3-carboxylic acid (8.36 g), N-hydroxybenzotriazole (10.2 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (12.8 g) and 4-dimethylaminopyridine (8.12 g) in N,N-dimethylformamide (300 ml) was stirred at 0° C. for 15 minutes. (2E,4E)- and (2Z,4E)-4-methyl-2,4-heptadien-1-ylamine (7.7 g) was added to the mixture. The solution was stirred at 0° C. for 2 hours and then at room temperature overnight. The mixture was evaporated in vacuo and the residue was diluted with water. The resulting precipitate was filtered and washed with water to give N-[(2E,4E)- and (2Z-4E)-4-methyl-2,4-heptadien-1-yl]-6-amino-3-pyridinecarboxamide (13.5 g).
