Versuchsvorschrift

To tert-butyl ((1S,3R)-3-((2-chloro-4-(propylamino)pyrimidin-5-yl)ethynyl)cyclohexyl)carbamate (P1, 155 mg), 4-amino-2-fluoropyridine (89 mg), tris(dibenzylideneacetone)dipalladium(0) (36 mg), 4,5′-bis(diphenylphosphino)-9,9′-dimethylxanthene (45 mg) and cesium carbonate (381 mg), 1,4-dioxane (5 mL) was added at room temperature, the reaction vessel was sealed, and then the mixture was stirred at 150° C. for 1 hour by using a microwave reaction system. The reaction mixture was cooled to room temperature, and then the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 88 to 30% hexane in ethyl acetate) to obtain tert-butyl ((1S,3R)-3-((2-((2-fluoropyridin-4-yl)amino)-4-(propylamino)pyrimidin-5-yl)ethynyl)cyclohexyl)carbamate (P2).
