Reaction Steps

To (1R,5S,7aS)-1-[3,5-bis(trifluoromethyl)phenyl]-5-[3-bromo-6-(dimethylamino)-5-iodopyridin-2-yl]tetrahydro-1H-pyrrolo[1,2-c][1,3]oxazol-3-one (50 mg, 0.075 mmol) in DMF (1 mL) was added isopropenylboronic acid pinacol ester (13.9 mg, 0.083 mmol), dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II)dichloromethane adduct (1.84 mg, 2.26 mmol) and potassium carbonate (0.5 M in water, 0.30 mL, 0.151 mmol). The system was stirred at 50° C. overnight before cooling and partitioning with water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, and concentrated before purifying by column chromatography to yield (1R,5S,7aS)-1-[3,5-bis(trifluoromethyl)phenyl]-5-[3-bromo-6-(dimethylamino)-5-(prop-1-en-2-yl)pyridin-2-yl]tetrahydro-1H-pyrrolo[1,2-c][1,3]oxazol-3-one (19 mg, 0.033 mmol). MS ESI calc'd. for C24H23BrF6N3O2 [M+H]+ 580.1. found 580.2.
