Reaction Steps

To a mixture of 2-(4-((4-chloropyrimidin-2-yl)amino)-1H-pyrazol-1-yl)-2-methylpropan-1-ol (200 mg) obtained in Step E of Example 347, 3-cyclopropyl-2-oxopyrrolidine-3-carbonitrile (110 mg) obtained in Step C of Example 103, cesium carbonate (490 mg) and 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (26 mg) in toluene (2.0 mL) was added tris(dibenzylideneacetone)dipalladium(0) (14 mg), 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 (130 mg).
