Procedure

To a mixture of 1-{5-chloro-2-[4-(3,5-dimethylpyridin-2-yl)piperazine-1-carbonyl]phenyl}-3-methylimidazolidin-2-one (116 mg) described in Preparation Example 241, pyrrolidin-2-one (35 mg), tripotassium phosphate (81 mg), tris(dibenzylideneacetone)dipalladium(0)-chloroform adduct (28 mg) and 2-di-tert-butylphosphino-3,4,5,6-tetramethyl-2′,4′,6′-triisopropyl-1,1′-biphenyl (13 mg) was added tert-butanol (1.5 mL), and the mixture was stirred with heating under reflux for 8 hr. After cooling, water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The solvent was evaporated, and the residue was purified by column chromatography (ethyl acetate:methanol) to give the title compound (62 mg).
