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 (0.12 g, 0.25 mmol) isolated in step 2, (5-methoxypyridin-3-yl)boronic acid (0.046 g, 0.30 mmol), 10% sodium carbonate (0.60 mL, 0.62 mmol), 1,4-dioxane (1.5 mL) and tetrakis(triphenylphosphine)palladium(0) (0.017 g, 0.015 mmol), the mixture was bubbled with N2 for 5 min and then heated at 100° C. for 2 hours. The resulting mixture was cooled to room temperature and then treated directly with 6.0 M hydrogen chloride in water (0.4 mL, 2 mmol) for ˜30 minutes. 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 60 mL/min) to give the desired single enantiomer product. LCMS calculated for C21H22ClN6O2 (M+H)+: m/z=425.1. found: 425.1. 1H NMR (DMSO-d6, 300 MHz) δ 8.27-7.99 (6H, m), 7.63 (1H, s), 5.71 (1H, m), 3.79 (3H, s), 3.40 (3H, s), 1.94 (3H, s), 1.44 (3H, d, J=6.9 Hz) ppm.
