実験手順
2-(4-Chloro-phenoxymethyl)-oxirane (50 mg) and of 3-(4-Trifluoromethyl-phenoxymethyl)-piperidine (70 mg, 1.0 equivalent) in 4 mL of methanol were heated in a sealed tube at 100° C. for 16 hours, cooled to room temperature, transferred to a round-bottomed flask, and concentrated in vacuo. The crude residue was purified by flash chromatography on silica gel using as eluent a gradient of ethyl acetate in hexane containing 1% ammonium hydroxide. 95 mg of 1-(4-Chloro-phenoxy)-3-[3-(4-trifluoromethyl-phenoxymethyl)-piperidin-1-yl]-propan-2-ol was obtained (79%). Data for this mixture of amino alcohol diastereomers: MS 444 (M++1).
