Reaction Steps

A mixture of (8-bromo-6-(trifluoromethyl)imidazo[1,2-a]pyridin-3-yl)((1S,4S)-2-oxa-5-azabicyclo[2.2.1]hept-5-yl)methanone (50.0 mg), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (40.0 mg), [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloride dichloromethane adduct (10.5 mg) and cesium carbonate (125 mg) in DME (2.5 mL) was stirred with microwave irradiation at 120° C. for 30 min. To the reaction mixture was added 0.1N hydrochloric acid, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (15.6 mg).
