Procedure

Into a microwave vial was added N-[1-(3-bromo-5-chloro-2-methoxy-4-methylphenyl)ethyl]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (0.046 g, 0.096 mmol), (5-fluoropyridin-3-yl)boronic acid (0.020 g, 0.14 mmol), 10% sodium carbonate solution (0.23 mL, 0.23 mmol), 1,4-dioxane (0.9 mL) and tetrakis(triphenylphosphine)palladium(0) (0.011 g, 0.0096 mmol). The mixture was bubbled with N2 for 5 min and then heated at 100° C. for 2 hours. The cooled reaction was treated directly with 6.0 M hydrogen chloride in water (0.2 mL, 1 mmol) at room temperature for ˜30 min. The mixture was diluted with MeOH, filtered and purified on Prep LCMS (XBridge C18 Column, eluting with a gradient of acetonitrile in water with 0.2% ammonium hydroxide, at flow rate of 30 mL/min) to give the desired product. LCMS calculated for C20H19ClFN6O (M+H)+: m/z=413.1. found: 413.1.
