Eco-benign method for synthesizing arylidene barbiturates has been developed by using ammonium chloride (NH4Cl) in stoichiometric amount, as an enolization activator, in water. Execution of methodology is simple, products obtained in high yields and the reactions are completed within 30 min. The new methodology does not involve any solvent/solvent extraction while solid products were yielded in all cases which were filtered and washed.
