Abstract
Procedure for obtaining urea derivatives, useful as herbicides, of general formula **(See formula)** in which it means a methyl, methoxy or isobutynyl radical, R2 represents an alkyl radical with up to 4 carbon atoms, an alkyl radical with up to 4 carbon atoms and bearing a hydroxyl group as a substituent, an alkenyl radical with 3 to 4 atoms carbon and substituted by 2 to 3 chlorine atoms, or the trichlorobenzyl radical, and X means a hydrogen or chlorine atom, where the corresponding derivatives of N-chloromethylphenyl-N'-alkyl-urea, which can carry Another substituent on the phenyl radical is reacted with the correspondingly substituted mercaptans or their metallic salts, mercaptides, in the presence of acid binding agents.
