Reaction Conditions

Reaction Steps

6-Phenylnicotinic acid (5.90 g) was dissolved in pyridine (150 ml), followed by addition of 4-methoxybutyric acid hydrazide hydrochloride salt (5.99 g) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride salt (8.51 g), and stirred at 60° C. for 10 hours. After the reaction solution was cooled to ambient temperature, the solvent was evaporated under reduced pressure. The resulting residue was washed with water, to afford 6-phenylnicotinic acid N′-(4-methoxybutyryl)hydrazide as pale yellow solid (6.06 g, 65%). The physico-chemical values are as follows.
