Benzyl-ethyl-piperidin-4-ylmethyl-amine (1.42 mmol) was dissolved in dichloromethane. 4-(5-Trifluoromethyl-pyridin-2-yloxy)-phenyl chloroformate (1.42 mmol, 0.451 g) (prepared from the corresponding, phenol by conventional methods) was added at room temperature. The reaction mixture was stirred overnight and evaporated to dryness. The crude product was subjected to column chromatography, ethyl acetate/heptane (1:3)→Triethylamine/ethyl acetate 1:9). The fractions containing the title product, was evaporated to dryness and HCl (g) in ethyl acetate was added and stirred for 16 hours. The solution was evaporated to dryness and dried in vacuum for 16 h. to give the title product. (58%, light yellow crystals). HPLC-MS m/z=514.1 (M+1), Rt: 3.27 min.
