Versuchsvorschrift

cis-2-(4-Chloro-benzenesulfonylamino)-cyclohexanecarboxylic acid amide (200 mg, 0.63 mmol), CsCO3 (250 mg, 0.76 mmol), and 1-bromomethyl-4-trifluoromethoxy-benzene (155 mg, 0.69 mmol) was stirred in acetonitrile (15 mL) at room temperature for 18 h. The reaction was then diluted with EtOAc (150 mL) and washed with H2O, brine, dried over Na2SO4 and concentrated to give a crude white wax. Further purification by flash chromatography (silica gel, 0.5%–1% MeOH/CHCl3) afforded the titled compound (205 mg) as a white solid in 67% yield: 1H NMR (DMSO-d6) δ 7.75 (d, 2 H, J=8.0 Hz), 7.59 (d, 2 H, J=8.0 Hz), 7.36 (m, 3 H), 7.21 (d, 2 H, J=8.0 Hz), 6.69 (s br, 1 H), 4.58 (AB2, 2 H, Δv=17, Jab=64 Hz), 3.89 (m, 1 H), 2.79 (s, 1 H), 2.44 (m, 1 H), 1.78 (m, 1 H), 1.66 (m, 2 H), 1.31 (m, 3 H), 0.98 (m, 1 H); MS m/e 491.03 (M+H)+.
