Procedure

To a solution of {3-[3-(2,2-diphenyl-ethylamino)-propoxy]-phenyl}-acetic acid methyl ester (3) (0.50 g, 0.0012 mol) in DMF (10 mL), was added 3-iodobenzyl bromide (0.36 g, 0.0012 mol) and powdered potassium carbonate (1.16 g, 0.0084 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 0.6 g in 81% yield. 1H NMR (CDCl3) δ 7.48 (d, 1H), 7.42 (s, 1H), 7.24 (m, 5H), 7.15 (m, 6H), 6.99 (d, 1H), 6.86 (m, 2H), 6.65 (s, 1H), 6.63 (dd, 1H), 4.16 (t, 1H), 3.67 (s, 3H), 3.60 (t, 2H), 3.58 (s, 2H), 3.52 (s, 2H), 3.05 (d, 2H), 2.61 (t, 2H), 1.81 (t, 2H); 13C NMR (CDCl3) δ 173.4, 160.5, 144.7, 143.7, 139.2, 137.3, 136.6, 131.2, 130.9, 129.8, 129.7, 129.6, 129.4, 127.8, 122.7, 116.9, 114.5, 95.6, 66.9, 61.1, 59.9, 53.5, 51.8, 51.1, 42.7, 28.2.
