Hydrochloric Acid → 2-(5-Bromo-2-oxopyridin-1(2H)-yl)propanoic acid

Participants

Reaction Steps

To a solution of ethyl 2-(5-bromo-2-oxopyridin-1(2H)-yl)propanoate (5.0 g, 18 mmol) in 40 mL of 1:1 THF/MeOH are rt was added 25 mL of 1N NaOH. The reaction was stirred at rt for 5 hours and was then acidified with 2N HCl to pH˜2. The solid formed was collected and was washed with water and EtOAc to give white solid (4.2 g, 94% yield) as desired product. MS (ESI pos. ion) m/z (MH+): 245.9. Calc'd Exact Mass for C8H8BrNO3: 244.97.
