N-[1-(3-bromo-5-fluoro-2-methoxy-4-methylphenyl)ethyl]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (21 mg, 0.044 mmol), [4-(methylsulfonyl)phenyl]boronic acid (13 mg, 0.066 mmol), potassium carbonate (15 mg, 0.11 mmol), water (0.2 mL), and 1,4-dioxane (0.40 mL) were added to a microwave vial. The mixture was degassed under nitrogen for 5 minutes. Tetrakis(triphenylphosphine)palladium(0) (5.1 mg, 4.4 μmol) was added to the mixture and the vial was then sealed and bubbled under nitrogen for 5 minutes. The mixture was heated at 80° C. overnight. The cooled reaction mixture was then treated with 4.0 M hydrogen chloride in water (0.5 mL, 2 mmol) and was stirred at room temperature for 30 minutes. Purification by preparative LCMS (pH 10) RP-HPLC (XBridge C18 Column, eluting with a gradient of acetonitrile in water with 0.2% ammonium hydroxide, at flow rate of 60 mL/min) afforded N-{1-[5-Fluoro-2-methoxy-6-methyl-4′-(methylsulfonyl)biphenyl-3-yl]ethyl}-9H-purin-6-amine (13 mg, 66%). LCMS calculated for C22H23FN5O3S (M+H)+: m/z=456.1. Found: 456.0.
