Synthesis of Some 2-Phenyl Imino Thiazolidine Condensed Pyrimidines

Abstract

2-Phenyl imino thiazolidin-4-one was prepared by well known method and treated with different aromatic aldehydes to yield corresponding benzylidine derivatives (1-3). These benzylidine derivatives when treated separately with urea and thiourea resulted in their corresponding thiazolidino pyrimidines (4–9) (Scheme II).
