Description

  

  Verfahren zur Herstellung eines     heterocyelischen        Carbaminsäurederivates.       Gegenstand vorliegenden Patentes ist ein  Verfahren zur Herstellung eines     heterocyeli-          schen        Carbaminsäurederivates.    Das Verfahren  ist dadurch gekennzeichnet, dass man eine Ver  bindung der Formel  
EMI0001.0006     
    mit einem     Carbaminsäurederivat    der Formel  
EMI0001.0008     
    umsetzt, worin X und Y zwei sieh im Verlaufe  des Verfahrens abspaltende Reste bedeuten.  



  Die erhaltene neue Verbindung, das     2-Pro-          pyl-4-methyl-pyrimidyl-    (6)     -dimethylcarbamat,     siedet unter 0,07 mm Druck bei 118 bis 120 .  Sie soll als Wirkstoff für Schädlingsbekämp  fungsmittel     Verwendung    finden.  



  <I>Beispiel:</I>  7.7 Teile des     Natriumsalzes    des     2-Propyl-4-          methyl-6-oxy-pyrimidins,    welches durch Um  setzen von     2-Propyl-4-methyl-6-oxy-pyrimidin     mit     Natriummethylat    erhältlich ist, werden     iri     Benzol suspendiert und nach Zugabe von 11  Teilen     Dimethylcarbaminsäurechlorid    etwa 12  Stunden unter     Rüekfluss    gekocht. Nachdem  man das gebildete Kochsalz durch Absaugen    abgetrennt hat, destilliert man das Benzol ab.

    Beim Fraktionieren des Rückstandes erhält  man das     2-Propyl-4-methyl-pyrimidyl-(6)-di-          methylearbamat    als farbloses Öl, welches unter  0,07 mm Druck bei 118 bis 120  übergeht.



  Process for the preparation of a heterocyclic carbamic acid derivative. The subject of the present patent is a process for the production of a heterocyclic carbamic acid derivative. The method is characterized in that one is a compound of the formula
EMI0001.0006
    with a carbamic acid derivative of the formula
EMI0001.0008
    converts, in which X and Y are two radicals which are split off in the course of the process.



  The new compound obtained, 2-propyl-4-methyl-pyrimidyl- (6) -dimethylcarbamate, boils at 118 to 120 under 0.07 mm pressure. It should be used as an active ingredient for pesticides.



  <I> Example: </I> 7.7 parts of the sodium salt of 2-propyl-4-methyl-6-oxy-pyrimidine, which can be obtained by reacting 2-propyl-4-methyl-6-oxy-pyrimidine with sodium methylate are suspended in benzene and, after adding 11 parts of dimethylcarbamic acid chloride, refluxed for about 12 hours. After the sodium chloride formed has been separated off by suction, the benzene is distilled off.

    When the residue is fractionated, 2-propyl-4-methyl-pyrimidyl- (6) -dimethylearbamate is obtained as a colorless oil which passes over at 118 to 120 under 0.07 mm pressure.
