実験手順

2.2 g of (2-methoxy-3-pyridyl)methyl cyanide, 35 ml of a 1N aqueous sodium hydroxide and 35 ml of methanol were stirred under heating at 100° C. for 1.5 hours. The mixture was cooled to room temperature, and then, 35 ml of a 5N aqueous hydrochloric acid was added thereto, and the solvent was evaporated. Ethanol was added to the residue and a solid was filtered off. Ethanol was evaporated, and ethanol was added again to the residue and a solid was filtered off. Ethanol was evaporated, to give 2.4 g of white crystals.
