Reaction Steps

Phenol (40 mg, 0.24 mmol) was added to a stirred suspension of 2-chloromethyl-6-(4-fluoro-phenyl)-6H-imidazo[1,2-c]pyrimidin-5-one (0.107 g, 0.38 mmol) and K2CO3 (0.160 g, 1.15 mmol) in ACN (3 mL). The mixture was stirred at 90° C. for 16 hours and then the solvents were evaporated in vacuo. 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 diethyl ether to yield 6-(4-fluoro-phenyl)-2-phenoxymethyl-6H-imidazo[1,2-c]pyrimidin-5-one (0.12 g, 90% yield) as a white solid. 1H NMR (500 MHz, CDCl3) δ ppm 5.20 (s, 2H), 6.70 (d, J=7.8 Hz, 1H), 6.98 (t, J=7.2 Hz, 1H), 7.03 (d, J=8.1 Hz, 2H), 7.12 (d, J=7.8 Hz, 1H), 7.19-7.25 (m, 2H), 7.27-7.34 (m, 2H), 7.38-7.45 (m, 2H), 7.83 (s, 1H).
