1,2-Dichloroethane → 2-Amino-N-methylpyridine-3-carboxamide

Participants

Reaction Steps

To the mixture of 2-aminonicotinic acid (2.0 g, 14.5 mmol), methylamine hydrogen chloride (1.47 g, 1.5 eq), EDC (4.49 g, 1.5 eq), HOBt (2.35 g, 1.2 eq) in DMF (20 mL) was added DIEA (7.6 mL, 3.0 eq). The mixture was stirred at room temperature overnight. The crude was concentrated and dissolved in EtOAc. It was washed with saturated NaHCO3. The solvent was removed and the crude was purified by silica gel chromatography (0%˜20% MeOH/DCM) to obtain the desired product 2-amino-N-methylnicotinamide (2.16 g, isolated yield ˜98%).
