Reaction Steps
A solution of methyl 6-aminopicolinate (10.65 g, 70 mmol, 1 eq) and sodium bicarbonate (13 g, 154 mmol, 2.2 eq) was dissolved in a mixture of acetone/water (2:1, 1M), and the solution cooled to 0° C. Benzyloxycarbonyl chloride (Cbz-Cl, 11.3 ml, 80.5 mmol, 1.15 eq) was added dropwise, and the reaction was warmed to room temperature and stirred for 18 hours. Water (200 mL) was added, and the resultant suspension was filtered to give a white solid. This solid was dissolved in methylene chloride, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide methyl 6-(benzyloxycarbonylamino)picolinate (17.5 g).
