YieldReaction ConditionsOperation in experiment
96% at 150℃; for 12h;Inert atmosphere; A mixture of 4,4?-bis(bromoethyl)biphenyl (1) (0.204 g, 0.592 mmol) and P(OEt)3 (1 mL, 6.27mmol) was heated at 150C for 12 h under N2. The mixture was purified over silica gel columnchromatography using ethyl acetate as eluant, giving 258 mg of 3.Yield : 96 %. 1H NMR (CDCl3, 400 MHz)delta 7.53 (d, J = 8.3 Hz, 4H), 7.36 (d, J = 8.3 Hz, 4H), 4.04(q, J = 7.1 Hz, 8H), 3.19 (d, J = 21.7 Hz, 4H), 1.27 (t, J = 7.1 Hz, 12H).
96% at 150℃; for 12h; 4,4?-bis(bromoethyl)-1,1?-biphenyl (0.204 g, 0.592 mmol) and P(OEt)3 (1 ml, 6.27 mmol) were stirred at 150 for 12 hours. The mixture was then cooled to room temperature and the product was purified by column chromatography on silica gel (ethyl acetate). The product was isolated as a colorless solid (0.258 g, 96).

YieldReaction ConditionsOperation in experiment
61% In butanone; at 20℃; for 3h; General procedure: A butanone solution (40 mL) of the linker (2 equiv.) and the corresponding 4-substituted pyridine (1 equiv.) was stirred at room temperature for 3 h 21, 22, 23, 25 and 26 were isolated after filtration and thorough washing with butanone, ethyl acetate and diethyl ether. In the case of 24, 27 and 28, the reaction mixture was evaporated, and the crude products purified by flash column chromatography on silica gel using CH2Cl2/MeOH (10/0.5) as eluent.
