实验步骤: (4-Chloro-3-(trifluoromethyl)phenyl)methanol (5.1 g, 24.22 mmol) was added in small portions to thionyl chloride (20 mL, 275 mmol). The reaction mixture was stirred at 50° C. for 18 h and heated under reflux for 23 h. The mixture was concentrated and dried under high vacuum to give the title compound as a colorless liquid (5.41 g). 1H NMR (400 MHz, CDCl3) δ ppm 4.58 (s, 2H), 7.50-7.51 (m, 2H), 7.71 (s, 1H). heated under reflux for 23 h The mixture was concentrated dried under high vacuum

实验步骤: To a solution of 4-(4-hydroxy-phenyl)-piperidine-1-carboxylic acid tert-butyl ester (1 eq) in anhydrous DMF is added NaH (1.1 eq) at room temperature. After 5 minutes, 1-chloro-4-chloromethyl-2-trifluoromethyl-benzene (1.1 eq) in DMF is added. The resulting mixture is stirred for 30 minutes. After aqueous work up, flash column chromatography (10% EtOAc/hexane) gave 4-[4-(4-Chloro-3-trifluoromethyl-benzyloxy)-phenyl]-piperidine-1-carboxylic acid tert-butyl ester.

The mixture is stirred for one hour and 10.0 g. of 4-chloro-3-trifluoromethyl benzyl chloride and 10 mg of potassium iodide are added. The mixture is stirred for a prolonged period and the solvent is removed in vacuo. The residual gum is dissolved in methylene chloride, dried over magnesium sulfate and filtered through magnesol. The filtrate is evaporated to give tan crystals which are recrystallized from ethanol giving the desired product as off-white crystals, mp. 181°-183° C.
