The ability of the pyridinium adduct of 1,3-dimethyl-5-methylenebarbituric acid (2) to undergo nucleophilic substitution reaction has been examined. Various types of nucleophiles, including cyanide, barbiturate, sulfide anions and 1,2-bis(diphenylphosphino)ethane substitute the pyridinium fragment in 2 leading to synthesis of new organic derivatives.

Keywords: 1,3-dimethyl-2,4,6(1H,3H,5H)-pyrimidinetrione (1,3-dimethylbarbituric acid), zwitterionic pyridinium adduct, nucleophilic substitution reaction
