Reaction Steps

A mixture of 5-bromo-2-chloropyrimidine (11.3 g), pyrrolidin-2-one (5 g), and K2CO3 (27.4 g) in 1-methylpyrrolidin-2-one (100 mL) was heated to 80° C. under nitrogen and stirred at this temperature overnight. After cooling to room temperature, the reaction mixture was concentrated to give an oil which was poured into water (50 mL). The resulting mixture was extracted with ethyl acetate (3×50 mL) and the combined organic phase was concentrated to afford an oil, which was purified by column chromatography on silica gel to afford the title compound. Yield: 592 mg (4% of theory).
