In 20 ml of N,N-dimethylformamide, 2.291 g (15.108 mM) of 4-piperidylmethanol hydrochloride, 4.48 g (18.1 mM) of bromodiphenylmethane, and 6.26 g (45.3 mM) of potassium carbonate were stirred together at 100° C. for 3.5 days and, then, at 150° C. for 2 hours. After cooling to room temperature, this reaction mixture was poured in water and extracted with 2 portions of ethyl acetate. The organic layers were pooled and dried over MgSO4 and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=3/1 to 2/1 to 1/1) to provide the title compound.
