반응 단계
2-Bromo-4,6-dinitro-2'-acetylamino-4'-(N,N-diethylamino) azobenzene (2.4 parts), copper (I) iodide (0.95 parts), anhydrous potassium acetate (1.5 parts), formamide (1.8 parts), acetic anhydride (2.0 parts) and n-butyl acetate (44 parts) are mixed together and heated, with stirring, to 110° C. during 15 minutes. The temperature is maintained at 110° C. for 2 hours when reaction is complete. The mixture is cooled to room temperature and poured into petroleum ether (boiling range 60-80° C.) (400 parts). The precipitate is collected, washed with petroleum ether (100 parts) and dried. 2-Cyano-4,6-dinitro-2'-acetylamino-4'-(N,N-diethylamino)azobenzene is obtained in 95% yield.
