TL;DR: In this paper, a three-component one-pot condensation of isatoic anhydride and aromatic aldehydes with primary amines or ammonium salts is used to synthesize 2,3-dihydroquinazolin-4(1H)-one derivatives in aqueous media via a threecomponent onepot condense of isaloic anoxide and aromatic anhydide.

Abstract: Hydroxyapatite nanoparticles (HAP NPs) are found to be an efficient catalyst for synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives in aqueous media via a three-component one-pot condensation of isatoic anhydride and aromatic aldehydes with primary amines or ammonium salts. The nanocatalyst (characterized by FT-IR, XRD, SEM-EDS and TEM techniques) is easily recyclable six times without the significant loss of catalytic activity. Other remarkable features include the wide range of functional group tolerance and good to excellent yields of the products under mild reaction conditions.
