Procedure

A mixture of 8-[1,4]-diazepan-1-yl-6-ethylquinoline dihydrochloride (0.32 g, 1 mmol, 1 equiv), 4-chloromethyl-2-phenylthiazole (0.21 g, 1 equiv) and Cs2CO3 (1.63 g, 5 equiv) in 5 mL of DMF was heated at 60° C. for 3 hours and then cooled to room temperature. EtOAc (˜70 mL) was added and the mixture washed with saturated aqueous NaHCO3 (70 mL) and brine (70 mL), dried over magnesium sulfate and concentrated. The residue was purified by silica gel flash column chromatography using 5% to 40% EtOAc in hexanes. Silica gel chromatography was repeated using 5% to 10% MeOH in EtOAc to afford the title compound as a light tan solid (0.22 g). 1H NMR (400 MHz, CD3OD) δ 8.65 (dd, 1H, J=1.8 and 4 Hz), 8.04 (dd. 1H, J=1.5 and 8.4 Hz), 7.91 (m, 1H), 7.90 (d, 1H, J=2.2 Hz), 7.41 (m, 3H), 7.36 (s, 1H), 7.31 (dd, 1H, J=4 and 8 Hz), 7.11 (s, 1H), 6.98 (s, 1H), 3.89 (s, 2H), 3.69 (m, 2H), 3.57 (t, 2H, J=5.87 Hz), 3.11 (m, 2H), 2.92 (t, 2H, J=5.3 Hz), 2.72 (q, 2H, J=7.0 Hz), 2.10 (m, 2H), 1.28 (t, 3H, J=7.0 Hz). MS (ES) m/z 429.2 (M+H+).
