A solution of 4'-(2-propenyl)biphenyl4-ol (1.22 g; Biochemistry 1987, 26(18), 5908) in ethanol (10 ml) at room temperature was treated with a solution of sodium hydroxide (0.215 g) in water (5 ml) and was then heated at reflux. A solution of (±)-α-(chloromethyl)-3-pyridinepropanol (1.0 g) in ethanol (5 ml) was added to the latter and the resulting mixture heated at reflux for 2 hours. The reaction mixture was cooled and then concentrated under reduced pressure. The residue was purified by column chromatography over silica eluting with dichloromethane:ethanol (95:5) to give a solid. Trituration with diethyl ether:methanol (9:1) gave the title compound as a colourless solid (0.256 g).
