Amounts used: 8 mL of acetic acid was saturated with sulfur dioxide, 190 mg of copper(I) chloride, 1.45 g (7.67 mmol) of 4-ethyl-3-trifluoromethyl-phenylamine dissolved in a mixture of 3 mL of acetic acid and 3 mL of concentrated hydrochloric acid, 0.635 g of sodium nitrite in 3 mL of water. Flash chromatography on silica using 0-20% ethyl acetate in hexanes afforded 0.9 g of the product as a white solid. LC-MSD spectrum not observed; HPLC retention time: 2.9 min.
