Procedure

38.3 parts by weight of cyclohexylthiol were added dropwise to a mixture of 72.3 parts by weight of 1-phenyl-4,5-dichloropyridazin-6-one in 300 parts by volume of methylene chloride, 3 parts by weight of triethylbenzylammonium chloride, and 13.2 parts by weight of sodium hydroxide in 150 parts by volume of water at room temperature (20° C.), and the reaction mixture was kept at this temperature for 12 hours, while stirring vigorously. The organic phase was separated off, washed with twice 100 parts by volume of water, dried and then concentrated. The residue was recrystallized from ethylacetate. 61 parts by weight of 1-phenyl-4-(cyclohexylthio)-5-chloropyridazin-6-one of melting point 125°-127° C. were obtained (compound A1).
