Abstract
Procedure for obtaining 2 (lH) -quinazolinone derivatives of formula Ij, **(See formula)** where R1 signifies a radical of formula II, **(See formula)** wherein o Z and Z1 are the same or different and signify a hydrogen, fluorine or chlorine atom, an alkyl or alkoxy radical of 1 to 3 carbon atoms, or a nitro or trifluoromethyl group, with the proviso that not more than one of Z and Z1 signify a trifluoromethyl or nitro group, or Z and Z1 are on adjacent carbon atoms and together signify a methylenedioxy group, or R1 signify a radical of formula III, **(See formula)** where Z2 signifies a hydrogen, fluorine or chlorine atom or an alkyl radical of 1 to 3 carbon atoms, x'means an oxygen or sulfur atom, R' means an alkyl radical of 1 to 5 carbon atoms, a cycloalkyl radical of 3 to 6 carbon atoms or a cycloalkylalkyl radical containing a total of 4 to 7 carbon atoms, where the cycloalkyl portion has 3 to 6 carbon atoms and the alkyl portion is a straight chain and has 1 to 3 carbon atoms, except that when R'means an alkyl radical of the 5 carbon atoms, x' means a sulfur atom, characterized in that it comprises oxidizing a compound of formula Ik, **(See formula)** wherein R', R1 and X' have the meanings indicated above, in an organic solvent that is inert under the reaction conditions, the procedure being carried out under substantially anhydrous conditions when the compound of formula Ik is a thione, conveniently at a temperature of 0º to 150ºC when the starting material is a -thione and conveniently a temperature of 0º to 120ºC when the starting material is an -one.
