Reaction Steps
A suspension of 2-(hydroxymethyl)-5-[(phenylmethyl)oxy]-4-oxo-1,4-dihydropyridine (3 g, 12.99 mmole) in chloroform (15 ml) was cooled to 0° C. under argon and treated with thionyl chloride (6.1 ml, 83.62 mmole). Within several minutes, a homogeneous solution was obtained. After stirring an additional 5 minutes, a cream colored solid precipitated. The cooling bath was removed, and the mixture was heated at reflux for 45 minutes. The mixture was cooled to 0° C. and the white suspended material was filtered, washed with chloroform and hexane and dried in vacuo. The yield of the title compound was 3.65 g.
