An efficient and environmentally benign one-pot component protocol has been presented for the synthesis of structurally diverse ,3-Dihydroquinazolin-4(1H)-ones with aldehydes and 2-aminobenzamide in a deep eutectic solvent (SnCl2 : urea: 1 : 2). The present protocol offers some advantages such as operational simplicity with easy workup, shorter reaction times, good to excellent yields with superior atom economy and environmentally benign reaction conditions.
