Reaction Steps
To a solution of methyl 4-chloropyridine-2-carboxylate (29.9 g, 174.9 mmol) in MeOH (15 mL) at 0° C. was added 2M methylamine in THF (437 mL, 874 nunol) dropwise. The reaction was allowed to stir at 0° C. for 3 h. The mixture was then concentrated and extracted with EtOAc (2×). The organic solutions were combined, washed with brine, dried over Na2SO4 and concentrated to give 4-chloro-N-methylpyridine-2-carboxamide (25 g, 84%). 1H NMR (300 MHz, d6-DMSO) δ: 8.85 (br s, 1H), 8.61 (d, 1H), 8.00 (d, 1H), 7.74 (dd, 1H), 2.81 (d, 3H).
