実験手順

5-[4-(4-Trifluoromethyl-phenyl)-piperazine-1-sulfonyl]-1H-indole (60 mg, 0.15 mmol), methyl bromo acetate (16 μL, 0.18 mmol) and cesium carbonate (95 mg, 0.29 mmol) were stirred in acetonitrile (10 ml) overnight at 70° C. The reaction mixture was diluted with ethyl acetate, washed with water, brine, dried (Na2SO4) and concentrated to provide {5-[4-(4-trifluoromethyl-phenyl)-piperazine-1-sulfonyl]-indol-1-yl}-acetic acid methyl ester (99%) as a yellow oil. 1H NMR (400 MHz, CDCl3) δ 8.11 (d, 1H) 7.60 (dd, 1H), 7.43 (d, 2H), 7.36 (d, 1H), 7.24 (d, 1H), 6.83 (d, 2H), 6.90 (d, 1H), 4.91 (s, 2H), 3.76 (s, 3H), 3.32-3.30 (m, 4H), 3.15-3.13 (m, 4H).
