반응 단계

N-(4-chloropyridin-2-yl)cyclopropanecarboxamide (0.8 g, 4.07 mmol), 6-chloro-[1,3]dioxolo[4,5-b]pyridin-7-amine (0.702 g, 4.07 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.282 g, 0.49 mmol), diacetoxypalladium (0.046 g, 0.20 mmol) and cesium carbonate (2.65 g, 8.14 mmol) were suspended in 1,4-dioxane (15 mL) and sealed into a microwave tube. The reaction was heated to 150 °C for 30 minutes in the microwave reactor and cooled to RT. The reaction mixture was diluted with EtOAc (50 mL) and washed with water (50 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford crude product. The crude product was purified by flash silica chromatography, elution gradient 0 to 100% EtOAc in isohexane. Pure fractions were evaporated to dryness to afford N-(4-(6-chloro-[1,3]dioxolo[4,5-b]pyridin-7-ylamino)pyridin-2-yl)cyclopropanecarboxamide (0.592 g, 43.7 %) as a white solid.
