실험 절차

To a solution of 1-(3-bromophenyl)-2-(4-morpholinyl)ethanone (7.8 g, 27.0 mmol) in THF (50 mL) was added methylamine (100 mL, 200 mmol, 2M solution in THF). After stirring for 15 min at room temperature, sodium cyanoborohydride (3.40 g, 54 mmol) was added followed by acetic acid (2 mL). The resultant mixture was stirred at RT for 5 days. The mixture was concentrated under reduced pressure. The residue was dissolved in ethyl acetate (200 mL) and washed with 5% NaHCO3 (200 mL) and brine (200 mL). The organic layer was dried (MgSO4) and concentrated to give [1-(3-bromophenyl)-2-(4-morpholinyl)ethyl]methylamine as yellow oil (8.10 g, 100%) which solidified after standing at room temperature. MS (ESI): 299.6 [M+H]+.
