실험 절차

A suspension of 6.44 g of (1,3-dioxolan-2-yl)-methyl-triphenylphosphonium bromide in 70 ml of diethyl ether is treated with 1.68 g of potassium t-butylate within 5 minutes while gassing with nitrogen. The orange suspension is stirred for 30 minutes, then cooled to 0° C. and treated within 10 minutes with a solution of 3.11 g of 6-[4-(octyloxy)phenyl]-3-pyridinecarboxaldehyde (prepared in accordance with Example 2) in 25 ml of diethyl ether. The reaction mixture is stirred at room temperature for a further 3 hours and then treated with 0.6 g of sodium hydrogen carbonate and with 20 ml of water. The organic phase is washed with water, dried over sodium sulfate and concentrated. The residue is taken up in hexane and 20 ml of 80 percent aqueous methanol. The phases are separated and the hexane phase is washed with 10 ml of 80 percent methanol, dried over sodium sulfate and concentrated. Chromatographic purification of the residue on 50 g of silica gel with hexane/ethyl acetate (vol. 9:1) gives 5-[2-(1,3-dioxolan-2-yl)vinyl]-2-[4-(octyloxy)phenyl]-pyridine.
