SYNTHESIS AND REACTIONS OF SOME 4-ARYLMETHYLENE-2-PHENYL-2'-AMINOPHENYL-2-IMIDAZOLIN-5-ONE DERIVATIVES

Some 4-arylmethylene-2-phenyl-2'-aminophenyl-2-imidazolin-5-ones Ia-c were prepared. Reactions of Ia-c with some Michael donors, acetic anhydride, chloroacetyl chloride, benzenesulphonyl chloride and bromine afforded compounds (IIa-c), (IIIa-c), (IVa-c), (Va-c) and (VIa-c), respectively. Treatment of the bromo-derivatives (VIa-c) with morpholine in acetic acid gave the corresponding morpholino derivatives (VIIa-c). The imidazolinones (Ia-c) undergo diazotisation and coupling with alkaline beta-naphthol to give azodyes (VIIIa-c).
