To a mixture of 3-iodo-6-methyl-2-[1-(9H-purin-6-ylamino)propyl]-4H-pyrido[1,2-a]pyrimidin-4-one (from example 3, step 2; 0.030 g, 0.065 mmol) and (3-fluorophenyl)boronic acid (Aldrich, 10.9 mg, 0.0780 mmol) in 1,4-dioxane (0.5 mL) was added a 1M solution of sodium carbonate (8.27 mg, 0.0780 mmol) in water (0.077 mL) and tetrakis(triphenylphosphine)palladium (0) (3.76 mg, 0.00325 mmol). The reaction mixture was heated at 100° C. overnight. After cooling to rt, the mixture was diluted with EtOAc, washed with water, brine, dried over MgSO4, and concentrated. The residue was purified on RP-HPLC at pH 10 conditions (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.15% NH4OH) to provide the desired product. LCMS calculated for C23H21FN7O (M+H)+: m/z=430.2. Found: 430.3. 1H NMR (DMSO-d6, 300 MHz) δ 8.11 (2H, m), 7.65 (1H, m), 7.45 (2H, m), 7.24 (4H, m), 7.08 (1H, m), 6.91 (1H, m), 5.17 (1H, m), 2.87 (3H, s), 1.79 (2H, m), 0.72 ((3H, t, J=7.2 Hz) ppm. 19F NMR (DMSO-d6, 282 MHz) δ −114 ppm.
