A novel protocol for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones from 2-aminobenzamides and aldehyde derivatives catalyzed by KOH/DMSO suspension has been developed. The present transition metal free methodology is operationally simple, scalable and varieties of 2,3-dihydroquinazolin-4(1H)-one derivatives were obtained in good to excellent yields in short reaction times.

A cascade synthesis of 2,3-dihydroquinazolin-4(1H)-ones has been developed from 2-aminobenzonitriles and carbonyl analogues using Gemini basic ionicliquid as green catalyst cum solvent at roomtemperature. Both aldehydes and ketones were condensed with 2-aminobenzonitriles affording good to excellent yields of products. Moreover, the ionicliquids can be reused up to 5th cycle without significant
