N-Bromosuccinamide → 3-(benzyloxy)-5-bromo-1-(4-butylphenyl)pyridin-4(1H)-one

Participants

Reaction Steps

To a solution of 3-(benzyloxy)-1-(4-butylphenyl)pyridin-4(1H)-one (705 mg, 2.1 mmol) in AcOH (21 mL) was added N-bromosuccinamide (414 mg, 2.3 mmol) and the reaction mixture was stirred at room temperature. After 1 h, the mixture was concentrated under reduced pressure and purified by flash chromatography (50 g Si02, 0-70% ethyl acetate/hexanes) to provide 3-(benzyloxy)-5-bromo-1-(4-butylphenyl)pyridin-4(1H)-one. LC/MS (M+H)+ 412/414.
