Reaction Steps

A mixture of the (3S,4S)-pyrrolidine-3,4-diol hydrochloride (0.773 g, 5.54 mmol), methyl 2,6-dichloropyrimidine-4-carboxylate (1.038 g, 5.01 mmol), and iPr2NEt (2.00 mL, 11.5 mmol) in acetonitrile (25 mL) was heated at 50° C. for 3 h. The reaction mixture was evaporated in vacuo and the residue chromatographed over silica gel with 25-75% acetone in hexanes. The product fractions were evaporated in vacuo to give methyl 2-chloro-6-((3S,4S)-3,4-dihydroxypyrrolidin-1-yl)pyrimidine-4-carboxylate as a light tan powder (1.132 g, 4.14 mmol, 83% yield). LC/MS: m/z=274.2 [M+H]+.
