5-AMINO-1-(4-FLUOROPHENYL)-1H-PYRAZOLE-4-CARBOXYLIC ACID Use and Manufacturing

Ethyl 5-amino-1-(4-fluorophenyl)-1H-pyrazole-4-carboxylate (22.18 g, 89 mmol) was suspended in 1 N aqueous solution of LiOH (178 ml_, 178 mmol) and methanol (200 ml_). The reaction mixture was refluxed for 17 hours, allowed to cool to room temperature and filtered. The filtrate was acidified to pH=7 with 2N HCI. A solid was collected by filtration and allowed to dry under reduced pressure to afford the title compound as a pale yellow solid (18.64 g, 95 percent yield), which was used without further purification.
