実験手順
2-(4-Chloro-benzenesulfonylmethyl)-1,3,4-trifluoro-benzene (1.0 g, 3.1 mmol, from example 8, step 2) and 6-bromo-1-hexene (1.5 g, 6.3 mmole) were dissolved in 20 mL THF and potassium t-butoxide (1M in THF, 6.2 mL) was added. The reaction mixture was stirred at room temperature for three hours. 50 mL water and 50 mL EtOAc were added. The organic layer washed with brine (50 mL), dried over Na2SO4 and concentrated. The product was purified by column chromatography using EtOAc/Hexane as eluent (gradient from 0/100 to 25/75 in 40 minutes, 0.65 g, 52%). 1H NMR (CDCl3, 400 MHz) δ 7.63 (d, j=8.05 Hz, 2H), 7.45 (d, j=8.05 Hz, 2H), 7.14 (m, 1H), 6.83 (m, 0.5H), 6.74 (m, 0.5H), 5.70 (m, 1H), 4.93 (m, 2H), 4.58 (d, j=5.1 and 6.5 Hz, 1H), 2.43 (m, 1H), 2.31 (m, 1H), 1.99 (m, 2H), 1.39 (m, 2H), 1.25 (m, 2H).
