Reaction Steps

Pyrrolidin-2-one (322 mg) was dissolved in N,N-dimethylformamide (4 mL), sodium hydride (159 mg) was added, and the mixture was stirred for 30 min. To the reaction mixture was further added [4-(3,5-dimethylpyridin-2-yl)piperazin-1-yl](6-fluoro-4-methylpyridin-3-yl)methanone (620 mg) described in Preparation Example 146, and the mixture was stirred at 100° C. for 5 hr. The reaction mixture was cooled, water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was purified by column chromatography (hexane:ethyl acetate) to give the title compound (125 mg).
