Abstract
Procedure for obtaining quinazoline derivatives of formula Ia, ** (see formula) ** Ia wherein R is 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, an alkylthio 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, R1 means an alkyl radical of 1 to 5 carbon atoms, but does not mean a tertiary alkyl radical in which the tertiary carbon atom is linked directly to the nitrogen ring atom, an allyl or propargyl radical, R2 means a radical phenyl or a substituted phenyl radical of formula II, ** (see formula) ** II 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 or bromine atom, 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) ** IIIa where R, R'1, R2 and n have the meanings indicated above, with an alkyl chlorocarbonate C1- 2, preferably in the presence of an acid binding agent and at a temperature of 60º to 100ºC.
