Reaktionsschritte
14.1 g of 1-bis(4-fluorophenyl)methoxy-2-chloroethane, 10.1 g of 4-hydroxypiperidine, 12 g of sodium carbonate and 0.2 g of sodium iodide were added to 200 ml of methyl isobutyl ketone, and the mixture was heated under reflux for 4 hours. At the end of this time, it was filtered, and the solvent was removed by distillation under reduced pressure. The resulting residue was purified by silica gel column chromatography. Elution with a 10:1 by volume mixture of ethanol and methylene chloride afforded 11.5 g (yield 66%) of the title compound as a pale yellow oily substance. p Infrared Absorption Spectrum (CHCl3), νmax cm-1 : 2920, 1600, 1505.
