Abstract
Procedure for obtaining quinazolinones of formula Ib, **(See formula)** where R 1 means an amino 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 of 1 to 5 carbon atoms or an alkoxy radical of 1 to 4 carbon atoms, with the proviso that R does not signify a hydrogen atom when R1º signifies a nitro radical, R1'means an alkyl radical of 1 to 5 carbon atoms, 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 trifluoromethyl 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 IIIa is cyclized, **(See formula)** where Rº1, R, R1'and R''have the meanings indicated above, with a C1-2 alkyl chlorocarbonate, in the presence of an acid binding agent, preferably in an organic solvent that is inert under the reaction conditions and at a temperature of 60º to 100ºC.
