Morpholine → 2-Bromo-1-(morpholin-4-yl)ethan-1-one

Participants

Reaction Steps

Bromoacetyl bromide (6.0 mL, 68.9 mmol) was dissolved in 30 mL of ether. Morpholine (7.0 mL, 80.3 mmol) was added dropwise to the above solution at −78° C. The reaction mixture was warmed to room temperature in 30 min. The resulting white solid was removed by filtration and washed with ether. The filtrate was washed with saturated sodium bicarbonate (20 mL×2). The combined aqueous phase was extracted with ether (20 mL×4). The combined organic extracts were washed with brine and dried over sodium sulfate. The solvent was removed in vacuo to give N-bromoacetyl-morpholine (3.73 g, 45%) as a clear oil.
