Reaction Steps

1-Methyl-5-phenoxy-1H-pyrazole-4-carboxylic acid ethyl ester (22.55 g; 91.37 mmol) was dissolved in THF/MeOH (1/1) and LiOH in water (7.67 g; 182.73 mmol) was added. After 16 hours at ambient temperature the reaction mixture was washed with EtOAc. The aqueous layer was acidified with 1 N HCl and extracted with EtOAc which was dried and evaporated afterwards.
