Procedure
A mixture of 2-((6-chloro-2-oxo-2,3-dihydropyrimidin-4-yl)(methyl)amino)propyl methanesulfonate (800 mg, 2.71 mmol) and K2CO3 (748 mg, 5.41 mmol) in acetonitrile (6 mL) was stirred at 80° C. for 3 h, cooled to room temperature and concentrated. Purification via Biotage Spla HPFC system (C18, mobile phase: 0.01% NH4HCO3/H2O, 10˜95% CH3CN, 9.5 min, 30 mL/min) afforded the title product as an orange solid.
