Abstract

Procedure for obtaining quinazolinone derivatives of formula Ib, **(See formula)** where R is a hydrogen, chlorine, fluorine or bromine atom, or an alkyl or alkoxy radical of 1 to 5 carbon atoms, n is 1 or 2, it means a hydrogen atom or an alkyl radical of 1 to 5 atoms of carbon, and R2 means a radical of formula **(See formula)** wherein Y means a hydrogen, fluorine, chlorine or bromine atom, or an alkyl radical of 1 to 4 carbon atoms, provided that when Y means a hydrogen atom or an alkyl radical and n means 1, R does not mean a hydrogen or halogen atom, characterized in that a compound of formula III is oxidized **(See formula)** where R, R''1, R2 and n have the meanings indicated above.
