Synthesis

62802-42-0

947533-45-1

Step A: 2-chloro-5-fluoropyrimidine (2 mL, 22.18 mmol) was dissolved in propionitrile (20 mL) and bromotrimethylsilane (6 mL) was added. The reaction mixture was transferred to a sealed vial and heated at 150 °C for 1 hour. Upon completion of the reaction, the mixture was allowed to cool to room temperature and subsequently concentrated under reduced pressure. The concentrated residue was partitioned between ethyl acetate (EtOAc) and saturated aqueous sodium bicarbonate (NaHCO3). The organic phase was separated, dried over anhydrous sodium sulfate and concentrated again under reduced pressure. The resulting residue was dissolved in hexane and cooled overnight at -30 °C to precipitate a solid. The solid was collected by filtration to afford the target product 2-bromo-5-fluoropyrimidine (2.03 g, 51% yield). The structure of the product was confirmed by 1H NMR (300 MHz, CDCl3): δ 8.49 (s, 2H).
