Procedure
Methyl 4-((5-bromo-1H-pyrazol-1-yl)methyl)benzoate (264 mg, 0.95 mmol), NaOH (200 mg, 5 mmol) were placed in a 100-mL flask with covered with MeOH and H2O (1:1) and stirred for 4 h at room temperature. The solution was then evaporated, taken up in water and acidified with 2M HCl with the resulting the solid filtered off yielding the desired product as a white solid (200 mg, 90%).
