Reaction Steps

N-[4-(4-fluorophenyl)-5-hydroxymethyl-6-isopropyl-pyrimidin-2-yl]-N-methyl-methanesulfonamide (50.0 g) and 48% hydrogen bromide (130.0 mL) were added to a reactor. The reaction mixture was stirred at 80° C. for 15 hours. The reaction was monitored with thin layer chromatography (ethyl acetate/n-hexane=1:2). The reaction mixture was cooled to 20˜25° C., stirred for over 1 hour, and then filtered under reduced pressure. The resulting white solid was washed with water (500.0 mL) and then dried under reduced pressure to obtain N-[5-bromomethyl-4-(4-fluorophenyl)-6-isopropyl-pyrimidin-2-yl]-N-methyl-methanesulfonamide as a white solid (55.3 g, yield 94%).
