| titleOfInvention | METHOD FOR PRODUCING N, N-DIMETHYL-O-PYRIMIDINYLCARBAMINIC ACID ESTERS |
| abstract | A novel process is provided for the preparation of O-pyrimidinyl N,N-dimethylcarbamates of the formula (I) <IMAGE> in which A, R, R<1>, R<2> and n have the meaning given in the text of the application, by reacting hydroxypyrimidines <IMAGE> with N,N-dimethylcarbamic acid halides of the formula (III> Hal-CO-N-(CH3)2 (III> in the presence of an acid acceptor. The novel process is characterised in that the reaction is carried out in the presence of an inorganic acid acceptor, in the presence of a catalytic amount of an acyclic and/or monocyclic amine and in the presence of a diluent at temperatures between 0 DEG C and 150 DEG C. The compounds of the formula (I) are known, potent insecticides. |
