Abstract

Process for obtaining herbicidal means for the destruction of weeds, in which the plants or the soil in which they grow are treated with a herbicidal medium, which contains a phytotoxic amount of an active compound derived from quinazoline of general formula I : ** (See formula) ** wherein R means an alkyl group with 2 to 4 carbon atoms, straight or branched chain and optionally substituted by chloro or methoxy, and R 'represents a hydrogen atom or the group - (CO) nA, where n is equal to 0 or 1 and meaning A a straight or branched chain alkyl, alkenyl or cycloalkyl group with 1 to 8 carbon atoms and optionally substituted by chlorine or a phenoxy group, which may in turn be substituted by chlorine or methyl, or a phenyl group optionally substituted by chlorine, bromine or nitro groups, characterized in that in a first step, the compound of general formula I is obtained by reaction of a 2-aminocyclohexanecarboxylic acid of formula ** (See formula) ** with an isocyanate of general formula R-N = C = O wherein R has the meaning indicated above, to transform the thus obtained 2-N'-alkylureidocyclohexanecarboxylic acid of general formula ** (See formula) ** wherein R has the meaning indicated above, by ring closure in the corresponding 2,4-dioxo-decahydroquinazoline of general formula ** (See formula) ** wherein R has the meaning indicated above, which is optionally converted, by reaction with an alkyl halide or an acyl chloride, to the corresponding substituted quinazoline derivative in position 1, and in a second step the resulting quinazoline derivative of general formula I is mixed with a solid or liquid filler.
