Procedure

To a solution of 5-chloro-2-methyl-3-(2-methyl-5-propynoyl-phenyl)-6-(6-methyl-pyridin-2-ylmethoxy)-3H-pyrimidin-4-one of Step C (67 mg, 0.16 mmol) in acetonitrile (2 mL) was added 2-hydroxy-2-methylpropionamidine HCl (34 mg, 0.25 mmol) and potassium carbonate (68 mg, 0.49 mmol) and the slurry was heated at 75° C. for eighteen hours. The reaction was returned to ambient temperature and filtered to remove excess salts. The filtrate was concentrated and purified via normal phase chromatography (ethyl acetate/heptane) to provide the title compound as a white solid (9.5 mg, 12% yield). MS (M+H): 492; 1H NMR (400 MHz, chloroform-d) δ ppm, 1.64 (s, 6H), 2.14 (s, 3H), 2.21 (s, 3H), 2.60 (s, 3H), 4.79 (s, 1H), 5.61-5.74 (m, 2H), 7.13 (d, J=7.43 Hz, 1H), 7.40 (d, J=7.04 Hz, 1H), 7.54-7.58 (m, 2H), 7.68 (s, 1H), 7.93 (s, 1H), 8.14 (d, J=7.83 Hz, 1H), 8.77 (d, J=5.09 Hz, 1H).
