Reaction Steps

A mixture of tert-butyl (S)-1-((R)-1-(3-(7-bromo-6-fluoro quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)pyrrolidin-3-ylcarbamate (0.10 g, 0.16 mmol), 1,3-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.073 g, 0.33 mmol) and cesium fluoride (0.065 g, 0.43 mmol) in 2-propanol (3.3 mL, 0.16 mmol) was degassed with nitrogen. Maintaining a nitrogen atmosphere, triethylamine (0.034 mL, 0.25 mmol) and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloromethane adduct (0.013 g, 0.016 mmol) were added, and the vessel sealed and heated at 100° C. for 17 hours. After cooling, the reaction mixture was diluted with ethyl acetate (10 mL), filtered through a plug of Celite®, and concentrated under reduced pressure. Purification of the residue by reverse phase chromatography on a C18 column (0-100% acetonitrile/water) provided the title compound (0.074 g, 72%).
