Procedure
A solution of 5-(chloromethyl)-N-(4-(difluoromethoxy)phenyl)-4-methoxypyrimidin-2-amine hydrochloride (0.14 g, 0.398 mmol) in DMF (1.5 mL) was added to a mixture of 6-hydroxyquinolin-2(1H)-one (0.08 g, 0.496 mmol) and Cs2CO3 (0.518 g, 1.590 mmol) in DMF (6.5 mL). The reaction mixture was stirred at room temperature for 18 h, then diluted with water and filtered. The filter cake was stirred in methanol/DCM (1:1) for 18 h, filtered, and dried to give 6-((2-((4-(difluoromethoxy)phenyl)amino)-4-methoxypyrimidin-5-yl)methoxy)quinolin-2(1H)-one as a beige solid (0.082 g, 45%). 1H NMR (400 MHz, DMSO-d6) δ ppm 11.67 (s, 1H), 9.76 (s, 1H), 8.35 (s, 1H), 7.96-7.70 (m, 3H), 7.36-6.93 (m, 6H), 6.51 (d, J=9.5 Hz, 1H), 4.94 (s, 2H), 3.99 (s, 3H). LCMS: R.T.=0.82; [M+H]+=441.1.
