Reaktionsschritte

2.00 g (6.61 mmol) of 4-[(4-chlorophenyl)-2-pyridylmethoxy]piperidine and 1.43 g (7.90 mmol) of ethyl 3-bromopropionate were dissolved in 10 ml of dioxane, and 1.09 g (7.89 mmol) of potassium carbonate was added to the mixed solution, and then the mixture was stirred under heating at an oil bath temperature of around 80° C. for 8 hours. After the reaction, the insolubles were filtered off, and the filtrate was concentrated under reduced pressure. The residue was separated by silica gel column chromatography using a solvent mixture of chloroform and methanol in the volume ratio 19:1 as are eluent. The desired fraction was concentrated under reduced pressure to give 1.78 g (67%) of ethyl 3-[4-[(4-chlorophenyl)-2-pyridylmethoxy]-1-piperidyl]-propionate.
