To a solution of methyl 6-(3-(benzyloxy)-2,6-difluorophenyl)-5-fluoropicolinate (1.0 equiv.) in methanol (0.1 M) was added 10% Pd/C (0.1 equiv.) in ethyl acetate. The reaction was placed under an atmosphere of hydrogen and stirred for 2 hours. Upon completion, the solution was filtered over a pad of Celite, the pad was washed with methanol, the filtrate was concentrated in vacuo to give methyl 6-(2,6-difluoro-3-hydroxyphenyl)-5-fluoropicolinate as a grey oil in 86% yield. LC/MS=284.0 (M+H), Rt=0.90 min.
