Versuchsvorschrift

When an equivalent amount of 3,5-dimethylpyrazole is substituted for 1-ethoxycarbonyl-2H-indazolin-3-one and 2-bromochloroethane is substituted for 1,2-dibromoethane in the procedure of Example 19 using tetrahydrofuran as solvent, 2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl chloride is isolated after column chromatography (3,5-dimethylpyrazole, Aldrich, 24%, C).
