Abstract
Procedure for obtaining quinazoline derivatives of formula Ib, **(See formula)** wherein 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, and (i) R''1 means an alkyl radical of 1 to 5 carbon atoms, an allyl radical or a propargyl radical, R'means a fluorine, chlorine or bromine atom, and m means 0 or 1, or (ii) R''1 signifies an isopropyl radical, R'signifies a fluorine, chlorine or bromine atom, an alkyl radical of 1 to 4 carbon atoms, an alkoxy radical of 1 to 4 carbon atoms, an alkylthio radical of 1 to 4 carbon atoms, or a nitro or trifluoromethyl group, and m means 1 or 2, provided that when m is 1, R'does not represent a halogen atom, and that when m is 2, the radicals R', which may be the same or different, mean a fluorine, chlorine or bromine atom, an alkyl radical of 1 to 4 carbon atoms or an alkoxy radical of 1 to 4 carbon atoms, by cyclization of a compound of formula IIIb, **(See formula)** where R', R''1, R2 and m have the meanings indicated above, with phosgene, preferably in an organic solvent that is inert under the reaction conditions, and conveniently at a temperature of 10º to 30ºC.
