To a solution of 5-chloro-6-(4-fluoro-benzyloxy)-2-methyl-3-(2-methyl-5-propynoyl-phenyl)-3H-pyrimidin-4-one of Step C (10 mg, 0.02 mmol) in acetonitrile (1 mL) was added 2-hydroxy-2-methylpropionamidine HCl (5 mg, 0.03 mmol) and potassium carbonate (10 mg, 0.08 mmol) and the slurry was heated at 75° C. for eighteen hours. After cooling to room temperature the reaction was 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 yellow oil (2.9 mg, 24% yield). MS (M+H): 495
