The mixture was heated at 50° C. overnight then concentrated in vacuo. The residue was chromatographed over silica gel with 25-75% acetone in hexanes. The product fractions were evaporated in vacuo to yield 2-chloro-6-(3-(hydroxymethyl)morpholino)pyrimidine-4-carboxamide as a pale tan solid (0.501 g, 1.84 mmol, 92% yield). LC/MS: m/z=273.2 [M+H]+.
