Reaction Steps
A mixture of 2-chloro-6-methyl-nicotinic acid (2 g, 12 mmol), N,O-dimethylhydroxylamine hydrochloride (1.14 g, 12 mmol), EDCI (2.68 g, 14 mmol), HOBt (81 mg, 16 mmol) and DIPEA (1 mL) in DCM (100 mL) was stirred at RT overnight. The reaction mixture was then partitioned between water and DCM, the organic layer separated, dried over anhydrous Na2SO4, filtered, and evaporated under reduced pressure. The crude residue was purified by flash chromatography (EtOAc/hexane, gradient from 0 to 25% in 25 minutes) to afford 2.4 g of 2-chloro-N-methoxy-6,N-dimethyl-nicotinamide as a white solid.
