N-(1,2,3,4-Tetrahydroquinolin-7-yl)-1,1′-biphenyl-4-carboxamide (Example 24) (66 mg, 0.2 mmol), potassium carbonate (41 mg, 0.3 mmol), potassium iodide (100 mg, 0.6 mmol) and 2-chloroethyl-n-propyl ether (38 ul, 0.3 mmol) in DMF (1 ml) were heated at 60° C. for 17 h then 100° C. for 48 h. After cooling to ambient temperature the reaction mixture was purified on a silica SPE column. Elution with 8% EtOAc/60-80° C. petroleum ether gave the title compound as a yellow solid. 1H NMR (250 MHz, CDCl3) δ (ppm): 7.93 (d, 2H), 7.72 (br, 1H), 7.70 (d, 2H), 7.63 (d, 2H), 7.48 (t, 2H), 7.40 (t, 1H), 7.03 (d, 1H), 6.92 (d, 1H), 6.74 (dd, 1H), 3.66 (t, 2H), 3.50 (t, 2H), 3.40 (m, 4H), 2.73 (t, 2H), 1.93 (qn, 2H), 1.58 (sx, 2H), 0.91 (t, 3H).
