Reaction Steps

Dissolve isonipecotic acid methyl ester, hydrochloride (43.7 g, 243 mmol) in a minimum amount of water. Add potassium bicarbonate (24.3 g, 243 mmol) and warm the solution on a steam bath for 20 minutes. Evaporate the water in vacuo, treat the residue with methanol and filter. Evaporate the filtrate in vacuo to give isonipecotic acid methyl ester as a oily yellow solid.
