Acetic Acid → [1-(4-Biphenylyl)-2-(4-morpholinyl)ethyl]methylamine

Participants

Reaction Steps

To a solution of 1-(4-biphenylyl)-2-(4-morpholinyl)ethanone (9.70 g, 34.4 mmol) in THF (100 mL) was added methylamine (2M solution in THF, 100 mL, 200 mmol). The mixture was stirred at room temperature for 15 min and then sodium cyanoborohydride (8.34 g, 133 mmol) and acetic acid (2.0 mL) were added. The resultant mixture was stirred at room temperature for 48 h. The mixture was diluted with ethyl acetate (200 mL) and washed with 5% NaHCO3 (200 mL) and water (200 mL). The organic layer was dried (MgSO4) and concentrated to give 10.59 g (100%) of the title compound as a yellow oil which solidified upon standing at room temperature. MS (ES) m/e 297.6 [M+H]+.
