Procedure

Potassium carbonate (27.8 g, 201 mmol) and water (3.62 g, 201 mmol) were added to a suspension of methyl 1-(2-fluoro-phenyl)-5-hydroxy-1H-pyrazole-3-carboxylate (31.6 g, 134 mmol) in methyl isobutyl ketone (323 ml) at room temperature. Then dimethyl sulfate (16.9 g, 134 mmol) was added slowly and the mixture was stirred for 2.5 h. Water was added and the phases were separated. The organic phase was evaporated to give 27.4 g of the title compound as a white solid.
