Methyl 6-[2,6-difluoro-4-(methylsulfinyl)phenyl]-5-fluoropyridine-2-carboxylate (37.0 mg, 0.112 mmol) was dissolved in THF (0.12 mL) and MeOH (0.12 mL), and 1.0 M aq. NaOH (0.56 mL, 0.56 mmol) was then added. The reaction mixture was stirred at room temperature for 50 min. The mixture was then neutralized with HCl (12 M) to pH=7 and concentrated under reduced pressure to remove all the solvents. The residue was dissolved in THF, dried, filtered and concentrated under reduced pressure to give the sub-title compound as a white powder. LCMS calc. for C13H9F3NO3S (M+H)+: m/z=316.0. Found: 316.2.
