Morpholine → 1-(3-Bromophenyl)-2-(4-morpholinyl)ethanone

Participants

Reaction Steps

To a solution of morpholine (4.72 mL, 54.0 mmol) in ether (40 mL) cooled at 0° C., was added dropwise 2-bromo-1-(3-bromophenyl)ethanone (7.53 g, 27.0 mmol) in a mixture of ether (100 mL) and dichloromethane (100 mL). The reaction mixture was then warmed to room temperature, stirred at room temperature for 1 h, and concentrated under reduced pressure to give white solid. The white solid was dissolved in dichloromethane (200 mL) and washed with 5% NaHCO3 (200 mL) and brine (200 mL). The organic layer was dried (MgSO4) and concentrated to yield 1-(3-bromophenyl)-2-(4-morpholinyl)ethanone 7.8 g (100%) as a white solid, which was used without purification. MS (ESI): 284.2 [M+H]+.
