A mixture of 2-bromo-1-fluoro-4-vinyl-benzene (8 g), morpholine (20 mL), Pd2(dba)2 (1.83 g), di-t-butyl-biphenylphosphine (1.2 g), K3PO4 (17 g) in DME (60 mL) was stirred at reflux for 4 h. The reaction mixture was cooled down to room temperature, diluted with methylene chloride, and filtered. The filtrate was concentrated in vacuo. The crude product was purified by Flash Chromatography of Biotage eluting with 7% ethyl acetate in hexanes to give the title compound as an oil (5 g).
