Reaction Conditions

Reaction Steps

A mixture of 4-(5-bromopentyl)-1,1′-biphenyl (328 mg, 1.08 mmol) and quinoline (1 mL) was heated at 60-70° C. for 12 hrs. The resulting mixture was washed with diethyl ether and then dissolved in water (30 mL). The aqueous solution was extracted with ethyl acetate (30 mL×5). Water was removed by lyophilization to afford 297 mg of the title compound. Yield: 64%. 1H NMR (300 MHz, CDCl3) δ 1.58 (m, 2H), 1.70 (m, 2H), 2.13 (m, 2H), 2.62 (t, J=7.5 Hz, 2H), 5.37 (t, J=7.8 Hz, 2H), 7.14-7.58 (m, 9H), 7.92 (d, J=7.5 Hz, 1H), 8.17 (m, 2H), 8.36 (m, 2H), 9.13 (d, J=8.4 Hz, 1H), 10.33 (d, J=5.4 Hz, 1H) ppm; 13C NMR (75 MHz, CDCl3) δ 26.1, 30.3, 30.9, 35.2, 58.1, 118.3, 122.5, 126.8, 126.9, 127.1, 128.7, 128.8, 129.9, 130.1, 131.1, 136.0, 137.5, 138.5, 140.7, 141.0, 147.3, 150.1 ppm.
