Reaction Steps
To a solution of 2-methoxypyridine-4-carboxylic acid 1 (1.0 g, 6.5 mmol) in CH3OH (30 mL) was added a few drops of SOCl2 at ambient temperature. The mixture was stirred under reflux for 16 hours and concentrated to give methyl 2-methoxypyridine-4-carboxylate 2. To the solution of 2-methoxypyridine-4-carboxylate 2 in CH3OH was added hydrazine monohydrate (2.0 mL, 37 mmol) at ambient temperature. The reaction mixture was stirred at ambient temperature for 16 hours and concentrated to give 2-methoxypyridine-4-carbohydrazide 3 as a white solid. Yield: 0.87 g, 80%.
