A series of new Schiff base derivatives were synthesized by reaction barbiturate derivatives (barbital and phenobarbital) with some aromatic aldehydes.Barbital and phenobarbital were treated with formaldehyde in ethanol as solvent to produce a and b.Then reaction compounds a or b with paratoluenesulfonylchloride in DCM and presence triethylamine to form (1,3(2H,4H)-diyl)bis(methylene)bis(4-methylb...
