In an analogous procedure in the preparation of 1-ethyl-2-methoxymethyl-3-benzyloxy-pyridin-4(1H)-one using 2-(1-ethoxymethyl)-3-benzyloxy-6-methyl-pyran-4(1H)-one 5.76 g (20 mmol, 1 eq.) and 4.65 g (60 mmol, 3 eq.) of 40% aqueous methylamine yielded the title compound (3.68 g, 61.1%) after purification by column chromatography on silica gel (eluant: 15% CH3OH/85% CHCl3) as a yellow oil.
