2-(5-bromo-2-fluorophenoxy)-N,N-dimethylethanamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 5-Bromo-2-fluoro-phenol (5.0 g, 26.2 mmol), 2-Dimethylaminoethylchlorid×HCl (5.66 g, 39.3 mmol) and K2CO3 (11.0 g, 78.5 mmol) are suspended/dissolved in 260 ml dry acetone and stirred at room temperature for 72 hours. Addition of aqueous NaHCO3 solution and extraction into ethyl acetate yields a crude product which is further purified by chromatography on silica. 1H-NMR (400 MHz; DMSO-d6): 7.41 (d, 1H), 7.20 (dd, 1H), 7.08-7.14 (m, 1H), 4.15 (t, 2H), 2.63 (t, 2H), 2.22 (s, 6H). MS (m/z, ES+): 262 (MH+).
