Procedure

A mixture of methyl 6-((3,5-dichloro-N-(4-fluorobenzyl)-2-hydroxyphenylsulfonamido)methyl)picolinate (0.185 g, 0.37 mmol), 1 N NaOH (2 mL), THF (2 mL) and MeOH (2 mL) was stirred at rt overnight. The reaction mixture was concentrated in vacuo and the residue was diluted with ethyl acetate and 1 N HCl. The organic layer was separated, washed with brine, dried over MgSO4, filtered and the filtrate solution was concentrated to give the desired product (0.18 g, 99%) as a colorless oil. 1H NMR (CDCl3) δ 8.12 (d, J=8.0 Hz, 1H), 7.88 (t, J=8.0 Hz, 1H), 7.58 (d, J=4.0 Hz, 1H), 7.55 (d, J=4.0 Hz, 1H), 7.45 (d, J=8.0 Hz, 1H), 7.06-7.03 (m, 2H), 6.93 (t, J=8.0 Hz, 2H), 4.64 (s, 2H), 4.40 (s, 2H). MS (ESI): 485.0 (M+H)+.
