Procedure

(6-Chloro-4,5-dimethylpyridazin-3-yl)hydrazine (W3.006; 8.00 g) was dissolved in DCM (400 ml) and admixed with methyl isothiocyanate (3.39 g). Subsequently, the mixture was stirred at RT for 24 h and left to stand over the weekend. The precipitate was filtered off, washed with DCM and dried in a drying cabinet at 45° C. 11.25 g of the title compound were obtained.
