Substuted N-(2,3-dioxo-1,2,3,4-tetrahydroquinazolinyl)benzamides (3a-g) and substituted N-(2-thiono-4-oxo-1,2,3,4-tetrahydroquinazolinyl)benzamides (4a-g) were synthetized in one step from the reaction of methyl anthranilate with 2-aryl-1,3,4-oxadiazolin-5-ones (1a-g) and 2-aryl-1,3,4-oxadiazoline-5-thiones (2a-g), respectively, in m-cresol at 150-160 deg C.Alternative routes leading to the formation of 3a and 4a are also reported.
