실험 절차

To 2-(4-chloro-2-chloromethyl-phenoxy)-1-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-ethanone (0.10 g, 0.23 mmol) in dimethyl formamide (2 ml) was added potassium carbonate (0.070 g, 0.51 mmol), tetrabutylammonium iodide (0.088 mg, 0.24 mmol) and finally methyl thioglycolate (0.02 ml, 0.25 mmol). The reaction was stirred at 50° C. for 19 hours. The reaction was diluted with ethyl acetate and washed with pH 7 phosphate buffer (0.05 M) and aqueous saturated sodium chloride. The organic layer was dried over magnesium sulfate and the title compound was isolated by chromatography on silica gel (0.046 g).
