摘要:
The present invention relates to a process for the sulfinylation of a pyrazole derivative, characterized in that 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-1H-pyrazole-3-carbonitrile (II) is reacted with a sulfinylating agent S in the presence of at least one amine acid complex wherein the amine(s) are selected from secondary and/or tertiary amines and the acid(s) are selected from hydrofluoric, hydrochloric, hydrobromic and hydroiodic acid and sulfonic acid derivatives, and with the addition of a halogenating agent, wherein S is [CF
