Procedure

A solution of methyl [3-(3-bromopropoxy)phenyl]acetate (1.0 g, 3.48 mmole) and [2-chloro-3-(trifluoromethyl)benzyl]-2,2-diphenylethylamine (1.63 g, 4.18 mmole) in 20 mL of acetonitrile was treated with potassium carbonate (0.72 g, 5.2 mmol). The reaction mixture was heated to reflux and stirred for 4 days. The reaction mixture was filtered, and the filtrate was concentrated in vacuo. The crude product was purified by flash chromatography (silica gel cartridge, Biotage 32-63 um, 60A) with 10% ethyl acetate:hexanes as the eluent to afford 1.69 g (81% yield) of the title compound as a viscous oil: 1H NMR (CDCl3, 400 MHz) δ 7.46-7.44 (d, 1H, J=7.7), 7.25-7.14 (m, 12 H), 6.91-6.84 (m, 2 H), 6.666.62 (m, 2 H) 4.154.09 (t, 1 H, J=7.6), 3.78 (s, 1 H), 3.69-3.66 (m, 5 H), 3.59 (S, 2 H), 3.15-3.13 (d, 2 H, J=7.7), 2.72-2.68 (t, 2 H, J=6.6), 1.87-1.80 (m, 2 H); MS (ESI) 597 (MH+); TLC (hexanes:Ethy acetate/9:1) Rf=0.36.
