To a solution of 2-chloro-5-(5-cyclopropyl-1H-pyrazol-3-yl)-benzoic acid ethyl ester (0.05 g, 0.17 mmol) in methanol (4 mL) was added KOH (0.12 g). The mixture was shaken at room temperature for 16 h. The mixture was acidified with 10% aqueous citric acid and extracted with ethyl acetate. The combined organic layers were washed with water and brine, and concentrated in vacuo to afford the title compound (0.06 g).
