To a solution of ethyl 2-(3-(1-methyl-1H-pyrazol-5-yl)phenyl)acetate (300 mg, 1.2 mmol) in MeOH (6 mL) was added aqueous NaOH (1.5 mL, 40 W %). The mixture was stirred at room temperature for 2 h. The reaction mixture was concentrated and the residue dissolved in water and adjusted pH to 5-6 with 2N of HCl. The solution was then extracted with EtOAc and the combined organic layers were concentrated to give the crude product which was used directly in the next step. LCMS (m/z): 231.1 (M+1).
