o-Bromoacetophenone reacts with the sodium salt of ethyl cyanoacetate to afford a-cyano-P-phenyl-A".Pbutenolide. This butenolide undergoes azo coupling with diazotized aromatic amines (ArNHJ to afford the hydrazo derivatives. These hydrazo derivatives (Ar= Ph, were transformed into the corresponding
