Procedure

2′-Fluoro-4′-(methylsulfonyl)-4-biphenylol (0.34 g, 65%) was prepared as an off-white solid from (4-hydroxyphenyl)boronic acid (0.30 g, 2.07 mmol), 1-bromo-2-fluoro-4-(methylsulfonyl)benzene (0.5 g, 1.98 mmol), 2M Na2CO3 (12 mL) and Pd(PPh3)4 (20 mg, 0.02 mmol) in DME (12 mL) in a manner similar to Example 1, Step 1. 1H NMR (400 MHz, CDCl3): δ 7.76 (dd, 1H, Ja=8.0 Hz, Jb=1.5 Hz), 7.74-7.69 (m, 1H), 7.64-7.58 (m, 1H), 7.47 (d, 2H, J=7.1 Hz), 6.94 (d, 2H, J=8.5 Hz), 4.94 (bs, 1H), 3.10 (s, 3H); LRMS (ESI), m/z 267 (M+H).
