Procedure

Potassium carbonate (22.0 g, 159 mmol) was suspended in acetonitrile, the suspension was added with 3-bromoaniline (8.71 mL, 80.0 mmol) and allyl bromide (23.7 mL 280 mmol), and the mixture was stirred at 80° C. for 14 hours. The reaction mixture was cooled to room temperature, then filtered through Celite, and sufficiently washed with ethyl acetate. The solvent was removed, and then the residue was purified by column chromatography (silica gel, ethyl acetate/hexane (1/40)) to obtain 3-bromo-N,N-diallylaniline (17.1 g, 67.9 mmol, yield 85%).
