反応手順
To a solution of methyl 3-amino-6-(2-fluoro-5-isopropylcabamoyl)phenyl)picolinate (1.0 equiv) in THF (0.5M), was added 1M LiOH (4.0 equiv). After stirring for 4 hours at 60° C., 1 N HCl (4.0 equiv.) was added and the THF was removed in vacuo. The resulting solid was filtered and rinsed with cold H2O (3×20 mL) to yield 3-amino-6-(2-fluoro-5-isopropylcabamoyl)phenyl)picolinic acid (98%). LCMS (m/z): 318.1 (MH+); LC Rt=2.4 min
