Procedure
15 g of montmorillonite K10 were added to a solution of 16 ml of trimethyl orthoformate in 80 ml of dichloromethane. A solution of 6.4 g (20 mmol) of 4-chloro-3-(4-chloro-3-formylphenyl)-5-difluoromethoxy-1-methyl-1H-pyrazole in 20 ml of dichloromethane was added dropwise at 5° C. to this mixture. The mixture was then stirred at room temperature overnight. The solids were then separated off and the clear reaction solution which remained was concentrated. Yield: 6.7 g.
