A solution of N-[1-(3-bromo-5-chloro-2-methoxyphenyl)ethyl]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (45 mg, 0.096 mmol) and (5-chloropyridin-3-yl)boronic acid (23 mg, 0.15 mmol) in water (0.5 mL) and 1,4-dioxane (1 mL) was treated with potassium carbonate (33 mg, 0.24 mmol) and tetrakis(triphenylphosphine)palladium(0) (11 mg, 9.6 mmol). The reaction mixture was degassed with nitrogen for 5 min and heated at 80° C. overnight. The reaction mixture was cooled treated directly with 6 M hydrogen chloride in water (170 μL, 1.0 mmol) and stirred at room temperature for ˜30 minutes. The reaction mixture was diluted slightly with methanol, filtered, and directly purified via preparative LCMS (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give the desired product (6 mg, 15%). LCMS for C19H17Cl2N6O (M+H)+: m/z=415.1. Found: 415.0; 1H NMR (300 MHz, DMSO-d6): δ 8.72 (d, J=1.8 Hz, 1H), 8.66 (d, J=2.3 Hz, 1H), 8.20-8.09 (m, 4H), 7.65 (d, J=2.1 Hz, 1H), 7.40 (d, J=2.6 Hz, 1H), 5.91-5.71 (m, 1H), 3.52 (s, 3H), 1.51 (d, J=7.0 Hz, 3H).
