실험 절차

To a solution of {3-[3-(2,2-diphenyl-ethylamino)-propoxy]-phenyl}-acetic acid methyl ester (3) (0.40 g, 0.001 mol) in DMF (10 mL), was added 3-trifluoromethylbenzyl bromide (0.24 g, 0.001 mol) and powdered potassium carbonate (0.96 g, 0.007 mol), the reaction mixture was heated and stirred at 45° C. for 18 hours. After cooling, the reaction mixture was diluted with water (30 mL) and extracted with EtOAc (3×25 mL). The combined organic extracts were washed with brine (15 mL), dried over Na2SO4, concentrated to an oil, which was purified by flash chromatography (8:2 Hexanes/EtOAc) to give the desired product as oil 0.43 g in 77% yield. 1H NMR (CDCl3) δ 7.40 (d, 1H), 7.37 (s, 1H), 7.24 (m, 7H), 7.19 (m, 6H), 6.83 (d, 1H), 6.62 (s, 1H), 6.59 (dd, 1H), 4.16 (t, 1H), 3.67 (s, 3H), 3.63 (s, 2H), 3.58 (t, 2H), 3.55 (s, 2H), 3.08 (d, 2H), 2.61 (t, 2H), 1.79 (t, 2H); 13C NMR (CDCl3) δ 173.4, 160.4, 144.7, 143.7, 142.2, 136.6, 133.8, 133.5, 131.9, 130.8, 130.2, 129.9, 129.8, 127.8, 126.8, 125.1, 125.0, 122.7, 116.8, 115.7, 114.5, 66.8, 61.1, 60.2, 53.5, 51.8, 42.6, 28.2.
