実験手順

To a mixture of the (S)-methyl 3-amino-2-hydroxypropanoate hydrochloride (0.333 g, 2.14 mmol) in acetonitrile (10 mL) was added 2,6-dichloropyrimidine-4-carboxamide (0.385 g, 2.01 mmol) and iPr2NEt (0.77 mL, 4.4 mmol). The mixture was heated at 50° C. overnight then cooled. The precipitated solid was filtered off, rinsed once with 2 mL acetonitrile, and air-dried to give (S)-methyl 3-((6-carbamoyl-2-chloropyrimidin-4-yl)amino)-2-hydroxypropanoate as a pale peach-colored powder (0.421 g, 1.53 mmol, 76% yield). LC/MS: m/z=275.1 [M+H]+.
