Potassium Carbonate → N-{3-[2,6-dichloro-4-(3,5-dimethyl-1,2-oxazol-4-yl)benzoyl]-1H-pyrrolo[2,3-c]pyridin-7-yl}cyclopropanecarboxamide

온도

90 °C

A mixture of N-[3-(4-bromo-2,6-dichlorobenzoyl)-1H-pyrrolo[2,3-c]pyridin-7-yl]cyclopropanecarboxamide (0.1 g, 0.2 mmol) and (3,5-dimethyl-1,2-oxazol-4-yl)boronic acid (0.037 g, 0.26 mmol) was taken in a vial. To the reaction mixture, 1,4 dioxane (3 mL), potassium carbonate (0.091 g, 0.6 mmol) and water (0.5 mL) were added. The whole reaction mixture was stirred with argon gas for about five minutes. Finally dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) (0.018 g, 0.02 mmol) was added to the reaction mixture, the vial was sealed properly and heated at 90° C. for about 4 hours. The reaction mixture was cooled to room temperature, followed by addition of water (25 mL), extracted with ethyl acetate (2×50 mL). The organic layer was dried over anhydrous sodium sulphate and concentrated under vacuum to get the crude. The crude was purified by preparative thin layer chloromatography using methanol (6%) in dicloromethane to obtain N-{3-[2,6-dichloro-4-(3,5-dimethyl-1,2-oxazol-4-yl)benzoyl]-1H-pyrrolo[2,3-c]pyridin-7-yl}cyclopropanecarboxamide (0.015 g, 15%).
