Procedure
While stirring at room temperature, a solution of 6.3 g of 1-(2-chloro-4-fluoro-5-isothiocyanato-phenylthio)-cyclopropanecarboxylic acid methyl ester in 30 ml of ethanol is added dropwise to a solution of 2.2 g of hexahydropyridazine in 30 ml of ethanol. After stirring for 30 minutes at room temperature, the reaction mixture is concentrated by evaporation in vacuo, yielding 7.9 g of 1-[2-chloro-4-fluoro-5-(1-hexahydropyridazinyl-thiocarbonylamino)-phenylthio]-cyclopropanecarboxylic acid methyl ester having a melting point of from +156° to +157° C.
