Procedure

To a solution of 5-chloro-6-(3-methoxy-benzyloxy)-2-methyl-3-(2-methyl-5-propynoyl-phenyl) -3H-pyrimidin-4-one from Example 6, Step E (32.5 mg, 0.08 mmol) in acetonitrile (1 mL) was added 2-hydroxy-2-methylpropionamidine HCl (16 mg, 0.12 mmol) and potassium carbonate (32 mg, 0.23 mmol) and the slurry was heated at 85° 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 (14.4 mg, 37% yield). MS (M+H): 507; 1H NMR (400 MHz, chloroform-d) δ ppm, 1.64 (s, 6H), 2.17 (s, 3H), 2.21 (s, 3H), 3.85 (s, 3H), 5.49-5.58 (m, 2H), 6.90 (d, J=7.43, 1H), 7.07 (s, 1H), 7.09 (s, 1H), 7.31-7.35 (m, 1H), 7.54-7.58 (m, 2H), 7.93 (s, 1H), 8.13 (d, J=6.65 Hz, 1H), 8.77 (d, J=5.09, 1H).
