Reaction Steps
The crude 4-chloro-1-(2-fluoro-phenyl)-5-methoxy-1H-pyrazole-3-carboxylic acid methyl ester obtained (330 mg, 1.16 mmol) obtained in step 1 was dissolved in 6 ml of dioxane and 5.8 ml of an aqueous 1 M solution of lithium hydroxide were added. The mixture was stirred for 30 min at 56° C. Acidic aqueous work-up gave 320 mg (100%) of the title compound.
