Abstract
A series of 2,3-dihydroquinazolin-4(1H)-ones has been synthesized using a simple, effective, one-pot, three component condensation of isatoic anhydride, aromatic aldehydes and amines in refluxing ethyl alcohol. It has been found that 15 mol% succinimide-N-sulfonic acid is the optimum amount of catalyst to obtain the high yield.
