Synthesis of 2,3-Dihydroquinazolin-4(1H)-ones Promoted by Polystyrene Sulfonic Acid %K Synthesis of 2 %K 3-Dihydroquinazolin-4(1H)-ones %K Polystyrene sulfonic acid %K Heterogeneous catalyst %K 2-Aminobenzamide %K Solid acid %R 10.22036/org.chem.2018.134699.1158 %X In this research, we have synthesized polystyrene sulfonic acid as a new heterogeneous solid acid. Then, we have synthesized 2,3-dihydroquinazolin-4(1H)-ones via condensation of 2-aminobenzamide and different aldehydes in the presence of polystyrene sulfonic acid. The major advantages of the present method are good yields, ecofriendly and easy work-up. %U https://www.orgchemres.org/article_76918_afc58774299b4d3a32e056f0fabf0e6a.pdf
