반응 단계
To a mixture of [4-(2,4-dimethylphenyl)piperazin-1-yl](4-iodophenyl)methanone (841 mg) described in Preparation Example 8, (R)-(+)-4-tert-butyloxazolidin-2-one (214 mg), potassium carbonate (553 mg) and copper (I) iodide (76 mg) were added toluene (2 mL) and N,N′-dimethylethylenediamine (100 μL), and the mixture was refluxed for 8 hr. After cooling, water was added to the reaction mixture, and the mixture was extracted with chloroform. The organic layer was washed with saturated brine, and the solvent was evaporated. The residue was purified by column chromatography (chloroform:methanol) to give the title compound (7 mg).
