Procedure
To a solution of methyl 3-bromo-4-(1-methyl-1H-pyrazol-5-yl)benzoate (275 mg, 093 mmol) in MeOH (10 mL) was added NaOH solution (2.5 M, 3.72 mL, 9.3 mmol). After 12 h at 25° C., the solution was partitioned between H2O-DCM and the pH of the aqueous phase was adjusted to ˜4 with 6N HCl solution. The aqueous phase was washed several times with DCM and the combined organic fractions were dried over Na2SO4 and concentrated to afford the title compound as a white solid (230.1 mg, 88%): LC-MS (ES) m/z=282 (M+H)+.
