After addition, the reaction mixture was heated to 150C for 20 hours. Then the reaction mixture was cooled to rt, and poured into water, and then adjusted to pH 7 with aqueous sodium hydroxide solution. The resulting mixture was filtered and the filter cake was dissolved in EtOAc. The mixture was stirred at it for a while and filtered. The filtrate was concentrated in vacuo. The crude was purified by silica column chromatography (PE/EtOAc (v/v) = 15/1) to give the title compound as a white solid (8.08 g, 97.0 %). The compound was characterized by the following spectroscopic data:MS(ESI, pos.ion)m/z: 226.0 (M+1), 228.0(M+3); exact mass of C9H5BrFN: 224.96.
