Procedure
To a stirred solution of 2,6-diethylaniline (10.0 g, 67.0 mmol) in acetic acid (50 mL) at ambient temperature was added bromine (10.4 mL, 201 mmol). The reaction was stirred overnight at ambient temperature. The reaction mixture was diluted with diethyl ether (200 mL) and washed with 5% sodium bisulfite (4×50 mL) and brine. The organic phase was dried with sodium sulfate and the solvents were removed in vacuo. The residue was chromatographed on silica gel, eluting with 9:1 hexane-ethyl acetate to give the title compound (3.28 g, 21 % yield).
