2-aminobenzoic acid (anthranilic acid) reacted with benzoyl chloride in pyridine to furnish 2-phenyl-4H-benzo[d][1,3]oxazin-4-one(I), which was heated with guanidine for 1 hour to give 4-oxo-2-phenylquinazoline-3(4H)-carboximidamide (II). (II) On reaction with N-(hydroxyalkyl) aryl-amides/ imides afforded the final compounds N-[(arylamido/ imido-2yl)alkyl]-4-oxo-2-phenyl-quinazolin-3(4H)-carboximidamides (III) in yields of 45 to 60%. The target compounds were examined for their effect on sugar metabolism.
