実験手順

To a solution of (4-fluorophenyl){2-[3-(phenylmethoxy)phenyl]ethyl}amine (0.643 g, 2.0 mmol) and [4-(2-bromoethoxy)phenyl]glyoxal (0.617 g, 2.4 mmol) was added trifluoroacetic acid (0.342 g, 3.0 mmol). The reaction stirred at room temperature for 4 hours. The reaction was quenched with saturated sodium bicarbonate and extracted with ethyl acetate. The organic layer was dried over MgSO4, filtered, concentrated, and purified by column chromatography (SiO2, 20% ethyl acetate/hexane) to provide the title compound (0.879 g, 78% yield): 1H NMR (CDCl3) 8.00 (d, 2H), 7.40 (m, 4H), 7.18 (m, 1H), 7.07 (d, 1H), 6.79-6.92 (m, 8H), 5.85 (s, 1H), 5.02 (s, 2H), 4.33 (t, 2H), 3.71 (m, 1H), 3.64 (t, 2H), 3.47 (m, 1H), 3.07 (m, 1H), 2.87 (m, 11H); ES−MS (m/z) 560 [M+H]+.
