Reaction Steps

24 g of 3,7-dichloroquinoline-8-aldoxime were dissolved in 250 ml of dimethylformamide, 12.5 g of cyclohexyl isocyanate were added dropwise at room temperature and the solution was then stirred at 50° C. for 5 hours. In the course of the reaction period, a further 12 g of cyclohexyl isocyanate were slowly added dropwise. 2 liters of water were added to the reaction solution, and the solid was filtered off under suction, suspended in a little methanol, again filtered off under suction and recrystallized from toluene with active carbon to give 26 g (72% of theory) of 3,7-dichloroquinoline-8-aldoxime cyclohexylcarbamate of melting point 152° C.
