A stirred mixture of 3-acetylamino-4-(2'-bromo-4',6'-dinitrophenylazo)-N,N-diethylaniline(4.8 parts), copper (I) iodide (2.0 parts), formaldoxime trimer (1.75 parts), 2,6-lutidine (2.15 parts), and nitrobenzene (150 parts) was heated to 95° C. for 10 hours when thin layer chromatography showed reaction to be complete. Isolation by the method of Example 1 gave 3-acetylamino-4-(2'-cyano-4',6'-dinitrophenylazo)-N,N-diethylaniline (infra red spectrum identical with that of authentic material). Similar results were obtained when the 2,6-lutidine was replaced by 2,4-lutidine (2.15 parts) and 2,4,6-collidine (2.4 parts).
