실험 절차

In a procedure analogous to Example B6, ethyl 1-isopropyl-5-methyl-1H-pyrazole-4-carboxylate (537 mg, 2.74 mmol) and lithium hydroxide (459 mg, 10.95 mmol) were combined to give 1-isopropyl-5-methyl-1H-pyrazole-4-carboxylic acid (32 mg, 70% yield) as an off white solid. MS (ESI) m/z: 169.0 (M+H+).
