Participants

Reaction Steps

Add sodium hydride (2.5 mmol, 2.5 eq) to a cooled solution of 5-bromo-N-methoxy-N,3-dimethyl-6-oxo-1,6-dihydropyridine-2-carboxamide (2, 1.0 mmol, 1 eq) in dimethylformamide (25 mL) and stir the reaction for 20 min. Add 4-methoxybenzyl chloride (1.2 mmol, 1.2 eq) and stir the reaction for 16 h. After completion, quench the reaction with water and extract with ethyl acetate. Remove the solvent and purify the crude by column chromatography to afford 5-bromo-N-methoxy-1-(4-methoxybenzyl)-N,3-dimethyl-6-oxo-1,6-dihydropyridine-2-carboxamide (3).
