Procedure
To a stirred solution of 2-ethylaniline (1.88 g, available from Aldrich) and sodium acetate (1.27 g) in acetic acid (20 ml) was added iodine monochloride (1 ml, available from Aldrich). The mixture was stirred at 20° C. for 90 min and then the solvent was removed in vacuo. The residue was partitioned between ethyl acetate (25 ml) and saturated aqueous sodium carbonate solution (25 ml). The organic layer was dried using a hydrophobic frit and the solvent was removed in vacuo. Purification by C18 SPE eluting with 20% acetonitrile in water gave the title compound as a purple solid (0.402 g).
