实验过程

Tetrakis(triphenylphosphine)palladium(0) (56.5 mg, 0.05 mmol) was added to 3-(2-chloro-5-fluoropyridin-4-yl)-5,5-dimethyl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazole (130 mg, 0.49 mmol), tert-butyl ((1R,3S)-3-carbamoylcyclohexyl)carbamate (119 mg, 0.49 mmol) and 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (56.6 mg, 0.10 mmol) and Cesium carbonate (478 mg, 1.47 mmol) in 1,4-dioxane (5.98 ml). Degassed for 5 mins under nitrogen and the resulting suspension was stirred at 120 °C for 2 hours in the microwave reactor. The reaction mixture was partitioned between water (20ml) and DCM (40ml) and separated using a phase separation cartridge. The organics were absorbed onto silica and purified by flash silica chromatography, elution gradient 0 to 60% EtOAc in heptane. Pure fractions were evaporated to dryness to afford tert-butyl ((1R,3S)-3-((4-(5,5-dimethyl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-3-yl)-5-fluoropyridin-2-yl)carbamoyl)cyclohexyl)carbamate (81 mg, 35.1 %) as a pale yellow solid.
