Organic polymers due to having diverse properties such as excellent thermal stability, large surface areas and synthetic designability have been found several applications in the areas of catalytic systems. [1-2]. Furthermore, magnetic nanoparticles have excellent magnetic properties and ultra-comfortable separation processes. These compounds are used as heterogeneous support and active site for modification of many catalytic systems and were applied in organic synthesis domains such as photocatalysis, photoelectrochemical catalysis, oxidation reactions, multicomponent reactions, enzyme catalysis, coupling reactions and chiral catalysis [3-4]. 1,2,4-triazoloquinazolinone as the major important fused N-heterocycle compounds have tremendous pharmacological applications and are in many of natural products [5]. In this study, catalytic application of porous organic polymer functionalized magnetic nanoparticles was investigated for the synthesis of 1,2,4-triazoloquinazolinone (Scheme 1).
