Ethanol → Ethyl 2-(5-bromopyridin-3-yl)acetate

Participants

Reaction Steps

5.0 g (23.1 mmol) of (5-bromopyridin-3-yl)acetic acid in 30 ml of ethanol and 25 drops of conc. sulfuric acid are stirred at boiling point for 16 h. For work-up, the reaction mixture is concentrated under reduced pressure, the residue is taken up in ethyl acetate and washed repeatedly with semiconcentrated sodium bicarbonate solution, the organic phase is dried over sodium sulfate, the drying agent is filtered off, the solvent is removed completely on a rotary evaporator and the product is dried under reduced pressure for 16 h.
