Procedure

A mixture of 6-bromo-9H-purine (0.1072 g, 0.54 mmol), 1-[8-(5-fluoropyridin-3-yl)quinolin-7-yl]ethanamine (0.072 g, 0.27 mmol), and N,N-diisopropylethylamine (0.05630 mL, 0.32) in ethanol (0.9 mL) was heated at reflux under nitrogen overnight. The mixture was evaporated and the resultant residue was purified on RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.05% TFA, at flow rate of 30 mL/minute) to give the desired product as a tris-TFA salt. LCMS calculated for C21H17FN7(M+H)+: m/z=386.2; found: 386.1. 1H NMR (DMSO-d6, 400 MHz) δ 9.40 (1H, s), 8.81 (1H, m), 8.65 (1H, s), 8.62 (1H, s), 8.50 (1H, s), 8.41 (2H, m), 8.11 (1H, d, J=8.8 Hz). 7.97˜7.84 (2H, m), 7.55 (1H, dd, J=8.4 and 4.4 Hz), 5.25 (1H, m), 1.58 (3H, d, J=6.8 Hz) ppm. 19F NMR (DMSO-d6, 376.28 MHz) δ −75.0 ppm.
