Procedure
10.2 mL benzylchloride was added to 10 g piperidine-4-carboxylic acid amide and 21.6 g potassiumcarbonate in 280 mL DMF at 5° C. The reaction was stirred over night at RT. The solvent was removed and the residue was dissolved in water and dichlormethane. The organic layer was separated and evaporated. The residue was purified by column chromatographie (silica gel, eluent: dichlormethane/methanol 95:5 to 90:10) to give 9.8 g of the desired product.
