실험 절차

To a mixture of 2-chloromethyl-5-benzyloxy-4-pyridone (1.0 g), tetrahydrofuran (10 ml) and water (10 ml) were added dimethylamine hydrochloride (1.31 g) and sodium hydroxide (0.64 g). After being stirred for 1.5 hours, the mixture was concentrated under reduced pressure to dryness. The residue was dissolved in methanol and the insoluble material was filtered off. The filtrate was evaporated in vacuo to give 5-benzyloxy-2-(N,N-dimethylamino)methyl-4-pyridone (1.0 g) as a powder.
