実験手順

1-Methyl-5-phenoxy-1H-pyrazole-4-carboxylic acid ethyl ester (22.6 g; 91.4 mmol) is dissolved in THF/MeOH (1/1) and LiOH in water (7.67 g; 183 mmol) is added. After 16 hours at ambient temperature the reaction mixture is washed with EtOAc. The aqueous layer is acidified with 1 N HCl and extracted with EtOAc. The organic layer is dried and evaporated.
