Abstract

An efficient synthesis of new barbiturate salts consist of 2-aminopyridinium moiety by an uncatalyzed three-component condensation reaction of C-H acids, pyrimidine-tetraones, and 2-aminopyridines in refluxing chloroform is reported. The reaction of pyrimidine-tetraones and 2-aminopyridines with ninhydrin in the formation of new barbiturate salts consist of 2-aminopyridinium moiety is also investigated. (C) 2012 Elsevier Ltd.
