A mixture of N-[1-(3-bromo-5-chloro-2-methoxy-4-methylphenyl)ethyl]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (0.032 g, 0.066 mmol, from Example 113, Step 2, Chiral intermediate), benzyl 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrole-2-carboxylate (0.027 g, 0.080 mmol), sodium carbonate (0.16 mL, 0.17 mmol), 1,4-dioxane (0.6 mL)/water (0.2 mL) and tetrakis(triphenylphosphine)palladium(0) (4.6 mg, 0.0040 mmol) was degassed with N2 for 5 minutes, then heated at 95° C. overnight. The mixture was diluted with EtOAc, washed with sat. NaHCO3, water, brine, and dried over Na2SO4 and concentrated. The crude product (20 mg, 50%) was purified by chromatography eluting with 0 to 40% EtOAc in CH2Cl2. LCMS calculated for C33H36ClN6O4 (M+H)+: m/z=615.2. found: 615.2.
