The substitution of the bromine atom in methyl ..beta..-bromoaroylpyruvates by urea is accompanied by cyclization of the substitution product. Depending on the reaction conditions, this leads either to 6-aroyl-5-hydroxyuracils or to 5-aryl-4-methoxycarbonyl-2,3-dihydro-2-imidazolones. The UV spectra were recorded on a Specord UV-Vis spectrometer in ethanol with the substances at concentrations of 10/sup -4/-10/sup -5/ M. The IR spectra were recorded in Vaseline oil on a UR-20 spectrometer. The PMR spectra were recorded in deuteroacetone on an RS-60 spectrometer with HMDS as internal standard. The mass spectra were recorded on a Varian Mat-311 spectrometer at 70 eV.
