Reaction Steps

1-[8-Chloro-5-(3-fluorophenyl)imidazo[1,5-a]pyridine-6-yl]ethanamine (23 mg, 79 μmol), 6-bromo-9H-purine (32 mg, 0.16 mmol, Aldrich 104981) and N,N-diisopropylethylamine (69 μL, 0.40 mmol) were stirred in ethanol (1.0 mL) and heated to 130° C. for 30 minutes in a microwave. The mixture was evaporated and the resultant residue was purified on RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give the desired product as a racemic mixture (10 mg, 30%). LCMS calculated for C20H16ClFN7 (M+H)+: m/z=408.1. found: 408.0. 1H NMR (300 MHz, DMSO-d6): δ 8.09 (m, 3H), 8.65 (m, 3H), 7.42 (m, 4H), 5.02 (br s, 1H), 3.30 (m, 1H), 1.42 (m, 3H).
