Abstract

2,3-Polymethylene-3,4-dihydro-4-quinazolones react with bromine and sulfur trioxide to give complexes involving the nitrogen atom, while bromination in acidic media and Vilsmeier-Haack formylation lead to replacement of the hydrogen atoms of the carbon atom in the α position. Their nitration and chlorosulfonation give 6-nitro- and 6-chlorosulfonyl-2,3-polymethylene-3,4-dihydro-4-quinazolones. Some of the chemical transformations of the synthesized compounds were studied.
