実験手順
Sodium 6-(2,4-difluorophenyl)naphthalene-2-sulfinate (Step 3, 486 mg, 1.49 mmol), (1S)-1-(2-bromophenyl)ethanol (260 mg, 1.29 mmol) and copper(I) iodide (1.23 g, 6.46 mmol) were combined in dimethylsulfoxide (10 mL) and degassed. The reaction was heated to 110° C. for 2 hours. The cooled reaction mixture was poured into conc. ammonia solution and extracted with diethyl ether (x4). The combined organic layers were washed with brine, dried over MgSO4 and evaporated in vacuo. The residue was purified by flash column chromatography on silica, eluting with 5% then 10% diethyl ether/dichloromethane, followed by trituration with isohexane. A second column, eluting with 60% diethyl ether/isohexane, followed by trituration with isohexane, gave the title compound (145 mg). 1H NMR (500 MHz, CDCl3) δ 8.56 (1H, s), 8.17 (1H, d, J=7.9 Hz), 8.06-7.98 (3H, m), 7.79-7.76 (3H, m), 7.66 (1H, t, J=7.5 Hz), 7.54-7.48 (2H, m), 7.03-6.95 (2H, m), 5.65 (1H, q, J=6.2 Hz), 2.51 (1H, s), 1.35 (3H, d, J=6.3 Hz); m/z (ES+) 407 [(M-OH)+].
