Participants

Reaction Steps

To a mixture of (4-bromo-2-methylphenyl)[4-(3,5-dimethylpyridin-2-yl)piperazin-1-yl]methanone (842 mg) described in Preparation Example 118, sodium iodide (650 mg) and copper(I) iodide (246 mg) were added toluene (2.2 mL) and N,N′-dimethylethylenediamine (1.62 mL), and the mixture was stirred with heating under reflux for 18 hr under a nitrogen stream. The reaction mixture was cooled, water was added, and the mixture was extracted with ethyl acetate. The solvent was evaporated from the organic layer, and the residue was purified by column chromatography (chloroform:methanol) to give the title compound (562 mg).
