Reaction Steps
To a solution of (3-Fluoro-5-methyl-phenyl)-dimethyl-amine (2.82 g, 18.4 mmol) in acetonitrile (28 mL) were sequentially added ammonium acetate (0.142 g, 1.84 mmol) and a solution of N-bromosuccinimide (3.27 g, 18.4 mmol) in acetonitrile (23 mL) drop-wise at 0° C. After 1 h., at r.t., the solvent was switched to EtOAc, and the solution was washed with saturated NaHCO3 (aq), dried (MgSO4), filtered, and concentrated in vacuo to give an orange, oily residue. Purification of this oil by flash chromatography (SiO2, 5% EtOAc/Hexanes) gave (4-Bromo-3-fluoro-5-methyl-phenyl)-dimethyl-amine as an ivory solid (3.96 g, 93%).
