The title compound was prepared from sodium 6-(4-fluorophenyl)naphthalene-2-sulfinate (2.2 g, 7.13 mmol) and 1-fluoro-2-iodobenzene (820 μL, 7.03 mmol) according to the method of Example 6 Step 4. Purification by flash column chromatography eluting with 60% dichloromethane/isohexane gave 2-(4-fluorophenyl)-6-[(2-fluorophenyl)sulfonyl]naphthalene (0.80 g, 30%). 1H NMR (500 MHz, CDCl3) δ 8.66 (1H, s), 8.20-8.18 (1H, m), 8.07 (1H, d, J=8.5 Hz), 8.03 (1H, s), 7.98 (1H, d, J=8.7 Hz), 7.94 (1H, d, J=8.7 Hz), 7.83 (1H, dd, J=1.7, 8.5 Hz), 7.71-7.62 (2H, m), 7.60-7.56 (1H, m), 7.38-7.30 (1H, m), 7.21-7.17 (2H, m), 7.14-7.05 (1H, m).
