Abstract
1-Alkyl-1-alkoxy-3-aryl ureas are prepared by reacting a 1-hydroxy-3-aryl urea with dimethyl or diethyl sulphate under alkaline conditions. The starting materials may be obtained by reacting the aryl isocyanate with hydroxylamine, preferably in the presence of a water-miscible organic solvent which does not react with the aryl isocyanate. In examples the aryl group is phenyl and phenyl substituted as follows: 2-methyl, 3-methyl, 4-methyl, 2-methoxy, 4-methoxy, 3-chloro, 4-chloro, 2, 5-dichloro and 4-bromo. Suitable isocyanate starting materials are listed. The final products are herbicides. Specification 852,422 is referred to.
