Versuchsvorschrift
300 mg (1.2 mmol) of 1-(2-fluoro-phenyl)-5-methoxy-1H-pyrazole-3-carboxylic acid methyl ester was dissolved in 3 ml of acetic acid. 162 mg (1.2 mmol) of sulfuryl chloride were added and the mixture stirred for 4 h at room temperature. The solvent was removed in vacuo and the residue subjected to acidic aqueous work-up. The obtained crude title compound (330 mg) was used in the hydrolysis step without further purification.
