    摘要: The invention relates to a method of preparing 1-alkyl-3-aryl-5-difluoromethoxy-1H-pyrazoles of the formula (I), wherein aryl represents a mono- or polysubstituted phenyl ring, and R1 represents C1-C4 alkyl. The inventive method is characterized by reacting, in a first reaction step, a β-ketoester of the general formula (II) with hydrazine and by successively reacting the reaction product obtained with chlorodifluoromethane and a compound R1-L, wherein R1 has the meanings indicated above and L represents the leaving group of a nucleophilic displacement reaction.
