Versuchsvorschrift

In a three-necked flask fitted with an overhead mechanical stirrer, a mixture of 1-(3-chloropropyl)piperidine (49.8 g, 0.308 mol), 4-nitrophenol (42.8 g, 0.308 mol) and potassium carbonate (212 g, 1.53 mol), in anhydrous DMF (200 mL) was heated to 94° C. and stirred for 18 h. The mixture was cooled to room temperature, then diluted with 2 L water. The organics were taken up in ethyl acetate and washed twice with 2N sodium hydroxide and then brine. The combined organics were dried over magnesium sulfate then concentrated under reduced pressure to give the title compound as a yellowish oil.
