(S)-[2-{1-[1-(4-Chloro-phenyl)-cyclobutylmethyl]-piperidin-3-yl }-1-phenyl-ethanol] (38 mg, 0.100 mmol) was dissolved in 1 mL of THF and cooled to 0° C. Potassium tert-butoxide was added (112 mg, 1.0 mmol) followed by methyl iodide in large excess (ca. 0.5 mL). After 30 minutes at 0° C., water (5 mL) and ether (5 mL) were added. Extractive workup gave, after concentration of the organic layers in vacuo and chromatography on silica gel using as eluent an EtOAc-hexane gradient with 1% ammonium hydroxide, the desired product 1-[l-(4-Chloro-phenyl)-cyclobutylmethyl]-3-(2-methoxy-2-phenyl-ethyl)-piperidine, 184, (28 mg, 70%). Data for this compound: MS 398 (M++1).
