실험 절차

5.88 g (0.020 mol) of 4-[(4,5-difluoro-2-methoxyphenoxy)methyl]piperidine hydrochloride, 7.7 g (0.021 mol) of 2-bromo-N-(triphenylmethyl)ethylamine and 6.91 g (0.050 mol) of K2CO3 in 40 ml of DMF are reacted. The reaction mixture is heated to 90° C. for 8 hours. It is cooled to room temperature, poured into 500 ml of water and extracted 3 times with ethyl acetate. The organic phases are combined, washed with water, dried over MgSO4 and filtered, and the solvent is evaporated off under reduced pressure. The product is obtained in the form of an oil after chromatography. Yield: 41.5%.
