Procedure

Into a microwave vial was added N-[1-(3-bromo-5-chloro-4-fluoro-2-methoxyphenyl)ethyl]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (85 mg, 0.17 mmol), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,6-dihydropyridine-1(2H)-carboxylate (65 mg, 0.21 mmol, Aldrich #706531), sodium carbonate (420 μL, 0.44 mmol), 1,4-dioxane (1 mL) and tetrakis(triphenylphosphine)palladium(0) (12 mg, 0.010 mmol). The mixture was bubbled with nitrogen for 5 min and heated at 90° C. overnight. The mixture was diluted with water, extracted with EtOAc, dried over magnesium sulfate and concentrated. Purification on silica gel using 0-100% EtOAc in hexane gave the desired compound (47 mg, 46%). LCMS calculated for C29H37ClFN6O4 (M+H)+: m/z=586.3. found: 587.2.
