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
