Procedure

150 mg (0.675 mmol) of 1-(2-fluoro-phenyl)-5-hydroxy-1H-pyrazole-3-carboxylic acid were dissolved in 5 ml of THF. 440 mg (1.35 mmol) of cesium carbonate and 90.2 mg (0.675 mmol) of pyrrolidine-1-carbonyl chloride were added and the mixture was heated to 50° C. for 4 h. Then the mixture was filtrated and the filtrate containing the title compound directly used in the next step.
