実験手順

A mixture of 2-amino-3-(4-methoxybenzyloxy)pyridine (4.6 g, 20 mmol) and ethyl 2methylphenylacetimidate hydrochloride (4.69 g, 22 mmol) in ethanol (80 ml) was heated under reflux for 2 hours. Evaporation of the solvent gave an oil which was taken up in chloroform, convened to the free base by washing with aqueous sodium bicarbonate, and purified by flash chromatography (chloroform/methanol) to obtain the product as a gum (0.38 g).
