Abstract

Procedure for obtaining quinazolinone derivatives of formula Ib, **(See formula)** where R01 means a nitro radical, an N-dialkylamino radical where each alkyl radical is from 1 to 4 carbon atoms, or an N-morpholino radical, R means a hydrogen, fluorine, chlorine or bromine atom, an alkyl radical from 1 to 5 carbon atoms or an alkoxy radical from 1 to 4 carbon atoms, with the proviso that R does not mean a hydrogen atom when R01 means a nitro radical, R'1 means an alkyl radical of 1 to 5 atoms carbon, except that it does not mean a tertiary alkyl group where the tertiary carbon atom is linked directly to the ring nitrogen atom, an allyl radical or a propargyl radical, and R'' means a phenyl radical or a substituted phenyl radical of formula II, **(See formula)** where Y means a fluorine, chlorine or bromine atom, an alkyl radical of 1 to 4 carbon atoms, an alkoxy radical of 1 to 4 carbon atoms or a trifluomethyl group, and Y'means a hydrogen, fluorine atom, chlorine or bromine, an alkyl radical of 1 to 4 carbon atoms, or an alkoxy radical of 1 to 4 carbon atoms, characterized in that a compound of formula IVa is reacted, **(See formula)** wherein R01, R, R81'and R''have the meanings indicated above, with a lower alkyl (C1-C5) carbonate such as urethane in the presence of a catalytic amount of a Lewis acid, such as zinc chloride at a temperature of at least 140ºC, and preferably between: 160º and 200ºC.
