Procedure
246 mg (1.00 mmol) 4-bromo-6-methoxy-pyridine-2-carboxylic acid methyl ester was dissolved in 5 mL MeOH and treated with 2.50 mL 4 M aqueous NaOH solution at RT for 12 h. The solvent was removed by distillation. the residue was taken up in water and acidified with 4 M aqueous hydrochlorid acid. The precipitate was filtered off, washed with water and dried.
