Procedure

A mixture of 6-bromo-9H-purine (0.0274 g, 0.138 mmol), 1-{5-chloro-8-[4-(2-methoxyethyl)piperazin-1-yl]quinolin-7-yl]ethanamine (0.024 g, 0.069 mmol), and N,N-diisopropylethylamine (0.02396 mL, 0.1376 mmol) in ethanol (0.2 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 C23H28ClN8O(M+H)+: m/z=467.2; found: 467.1. 1H NMR (DMSO-d6, 400 MHz) δ 9.70 (1H, br s), 8.98 (1H, s), 8.50 (1H, d, J=8.0 Hz), 8.21 (2H, m), 8.02 (1H, s), 7.66 (1H, dd, J=8.4 and 4.4 Hz), 6.41 (1H, m), 4.42˜3.02 (12H, m), 3.33 (3H, s), 1.55 (3H, d, J=6.4 Hz) ppm.
