Abstract

Procedure for obtaining quinazoline derivatives of formula Ic, **(See formula)** where R'' means a hydrogen, fluorine, chlorine or bromine atom, an alkyl radical of 1 to 5 carbon atoms, an alkoxy radical of 1 to 4 carbon atoms, or a nitro, cyano or trifluoromethyl group, n is 1 or 2, with the proviso that when n is 2, each of the radicals R'', which may be the same or different, 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, R'''1 means an alkyl radical of 1 to 5 carbon atoms, R2 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 Y1 means a hydrogen, fluorine, chlorine atom 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 IV is oxidized, **(See formula)** where R'', R'''1, R2 and n have the meanings indicated above, preferably with manganese dioxide or potassium permanganate, preferably in an organic solvent that is inert under the reaction conditions and conveniently at a temperature of 15º to 30ºC.
