(Z)-1,2-Dimethyl-4-(4-methoxybenzylidene)-1H-imidazol-5(4H)-one underwent a condensation reaction with aromatic acyl chlorides, forming keto derivatives that were structurally similar to chromophores of red fluorescent proteins, as well as to the products of their maturation and/or degradation. The reverse reaction of the obtained products was observed upon treatment with aqueous alkali.
