実験手順

To a mixture of 3-cyclopropyl-2-oxopyrrolidine-3-carbonitrile (18 g) obtained in Step C of Example 103, 2,4-dichloropyrimidine (17 g), cesium carbonate (76 g) and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (4.1 g) in tetrahydrofuran (300 mL) was added tris(dibenzylideneacetone)dipalladium(0) (2.1 g), and the mixture was stirred overnight at 85° C. 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 (hexane/ethyl acetate) to give the title compound (23 g).
