A series of 5‐benzylidenepyrimidine‐2,4,6(1H,3H,5H)‐trione and 5,5′‐(arylmethylene) bis[6‐aminopyrimidine‐ 2,4(1H,3H)‐dione] derivatives were synthesized via the three‐component reactions of aromatic aldehyde, 6‐aminopyrimidine‐2,4‐dione and Medrum's acid in aqueous media in the presence of triethylbenzylammonium chloride. The structures of the products were affected by substituents of aromatic aldehydes
