Procedure

150 mg (0.635 mmol) of methyl 1-(2-fluoro-phenyl)-5-hydroxy-1H-pyrazole-3-carboxylate were dissolved in 8 ml of THF. 207 mg (0.635 mmol) of cesium carbonate and 400 mg (2.96 mmol) of bromomethyl-cyclopropane were added and the mixture was heated to 50° C. for 6 h. Then the mixture was filtrated and the solvent removed in vacuo. The crude title compound was used in the next step without further purification.
