A simple, green and environmentally benign procedure was developed for the synthesis of 2,3-dihydro-2-phenylquinazolin-4(1H)-ones using catalytic amounts of succinimide-N-sulfonic acid via the cyclocondensation of 2-aminobenzamide with an aldehyde. The present methodology offers several advantages such as high yields, simple procedure, low cost, short reaction times, mild reaction conditions, and use of a reusable catalyst.
