Versuchsvorschrift
In analogy to the procedure described for example 2 e], 5-(tert-butyl-dimethyl-silanyloxymethyl)-1,4-dimethyl-3-(4-trifluoromethyl-phenyl)-1H-pyrazole was treated with tetrabutylammonium fluoride in THF to yield [2,4-dimethyl-5-(4-trifluoromethyl-phenyl)-2H-pyrazol-3-yl]-methanol as yellow oil.
