Procedure

10 mmol of 2-(benzofuran-3-yl)-1-bromoethane, 9.62 mmol of tert-butyl 4-piperidyl-carbamate, 2.65 g of potassium carbonate and 0.65 g of tetrabutylammonium sulphate are added to 10 ml of toluene. After refluxing for 12 hours, the mixture is taken up in water. The organic phase is then washed with water, dried and then filtered. Evaporation under reduced pressure allows the expected product to be isolated.
