The reaction mixture was stirred at RT for 1 h. The mixture was diluted with saturated Na2CO3 and extracted with EtOAc. The organic layer was washed with brine, and dried over sodium sulfate and concentrated in vacuo. The crude product was obtained as yellow oil. MS m/z=367, 369 M+, Calculated for C10H9BrF6N2O: 367.09.
