An investigation of the isomeric change of N2-arylideneorthanilamides has led to the synthesis of a new series of 1:2:3:4-tetrahydro-4-oxoquinazolines from which the corresponding quinazol-4-ones have been obtained by oxidation. Based on the present investigation, a new synthesis of 2-(o-aminophenyl)-3H-quinazol-4-one (VI) is also reported.
