Reaction of hydroxyglycine with 2-aminobenzophenones gives 1,2-dihydro-4-phenyl-quinazoline-2-carboxylic acids in high yields and under mild conditions. These can be smoothly converted into the corresponding 3,4-dihydro isomers and into quinazoline derivatives via rearrangement and oxidation by air, respectively.
