Abstract
By quaternization of 1-alkyl(aryl, aralkyl)-2-methyl-4, 5-diarylimidazoles with α-bromo ketones and by subsequent cyclization of the quaternary salts of imidazole, a number of arylpyrrolo[1,2-a]imida~ zoles were obtained. A study was made of the effect of different bases on the process of cyclization and the yield of pyrroloimidazole derivatives. The structure was established of certain intermediate products of the reaction involving the closure of the pyrrole ring.
