Water → 1-(4-Biphenylyl)-2-(4-morpholinyl)ethanone

Participants

Reaction Steps

Morpholine (1.67 g, 19.1 mmol) in anhydrous ether (20 mL) was added dropwise to a solution of 1-(4-biphenylyl)-2-bromoethanone (2.63 g, 9.56 mmol) and triethylamine (TEA) (2.90 g, 28.68 mmol) in anhydrous ether (50 mL) at 0° C. over 30 min. The reaction mixture was then warmed to room temperature. After stirring for 2 h, water (80 mL) was added and the aqueous layer was extracted with ethyl acetate (2×60 mL). The combined organic layer was dried over MgSO4 and concentrated to yield the title compound as a light yellow solid (2.52 g, 93%), which was used without further purification. MS (ES) m/e 281 [M+H]+.
