Versuchsvorschrift
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 (3,5-difluorophenyl)boronic acid (Aldrich, 12.3 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 C23H20F2N7O (M+H)+: m/z=448.2. Found: 448.3. 1H NMR (DMSO-d6, 300 MHz) δ 8.06 (2H, m), 7.61 (1H, m), 7.38 (1H, m), 7.14 (5H, m), 6.88 (1H, m), 5.08 (1H, m), 2.83 (3H, s), 1.75 (2H, m), 0.70 ((3H, t, J=7.8 Hz) ppm. 19F NMR (DMSO-d6, 282 MHz) δ −111 ppm.
