Procedure

To a solution of 2,4-dichloro-5-iodopyrimidine (3.0 g; 10.9 mol) in acetonitrile (35 mL) was added triethylamine (1.32 g, 1.82 mL, 13.1 mmol), followed by (R)-2-aminopropanol (0.88 g, 11.8 mmol). The mixture was stirred at room temperature for 24 h and was then diluted with ethyl acetate, followed by extraction with brine, 10% aqueous citric acid, and aqueous sodium bicarbonate. After drying over sodium sulfate, the solvent was evaporated and the residue was purified by column chromatography to give the title compound (3.0 g, 88% yield).
