Popis:	Synthesis of 2,3-dihydroquinazolin-4(1H)-ones using H3BO3/montmorillonite K10 (H3BO3/mont K10) catalyst has been reported. H3BO3/mont K10 and H3BO3/mont K30 have been prepared and used as catalysts in the reaction between anthranilamide and benzaldehyde to prepare 2-phenyl-2,3-dihydroquinazolin-4(1H)-one. The catalysts have been characterized for their physico-chemical properties by XRD, IR, BET surface analysis, TGA, SEM, and DRIFTS. H3BO3/mont K10 has shown better catalytic activity among the catalysts tested for the synthesis of 2-phenyl-2,3-dihydroquinazolin-4(1H)-one. The reaction conditions have been optimized for 2-phenyl-2,3-dihydroquinazolin-4(1H)-one and the reusability of H3BO3/mont K10 has also been investigated. Several 2,3-dihydroquinazolin-4(1H)-one derivatives have been synthesized in good to excellent yields using the optimized reaction conditions.
