実験手順

To a solution of (3R)-1-(2-chloropyrimidin-4-yl)-3-ethyl-2-oxopyrrolidine-3-carbonitrile (200 mg) obtained in Step A of Example 8, 5-aminopyridine-2-carboxamide (130 mg) obtained in Step A of Example 350, cesium carbonate (520 mg) and 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (75 mg) in tetrahydrofuran (5.0 mL) was added tris(dibenzylideneacetone)dipalladium(0) (73 mg), and the mixture was stirred overnight at 80° C. under argon atmosphere. The insoluble substance was removed by filtration through Celite, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, hexane/ethyl acetate), and recrystallized (diisopropyl ether/ethanol) to give the title compound (25 mg).
