Reaction Steps

N-chlorosuccinimide (32.9 mg, 0.25 mmol) was added to a stirred solution of 6-(4-fluoro-phenyl)-2-phenoxymethyl-6H-imidazo[1,2-c]pyrimidin-5-one (75 mg, 0.22 mmol) in DMF (3.5 mL). The mixture was stirred at 150° C. for 15 minutes under microwave irradiation. The solvent was evaporated in vacuo and the crude product was purified by flash column chromatography (silica; AcOEt in DCM with a gradient of 0/100 to 20/80). The desired fractions were collected and the solvents evaporated in vacuo. The product was triturated with DIPE to yield 3-chloro-6-(4-fluoro-phenyl)-2-phenoxymethyl-6H-imidazo[1,2-c]pyrimidin-5-one (46 mg, 56% yield) as a white solid. 1H NMR (400 MHz, CDCl3) 8 ppm 5.12 (s, 2H), 6.62 (d, J=7.9 Hz, 1H), 6.98 (tt, J=7.4, 0.9 Hz, 1H), 7.03-7.07 (m, 2H), 7.06 (d, J=7.6 Hz, 1H), 7.17-7.25 (m, 2H), 7.27-7.34 (m, 2H), 7.35-7.43 (m, 2H).
