Reaction Steps

To a solution of compound 305 (670 mg, 2.4 mmol) in dry THF (11 mL) were added phenyl boronic acid 306b (439 mg, 3.6 mmol), palladium acetate (7 mg, 0.03 mmol), triphenyl phosphine (16 mg, 0.06 mmol), and sodium carbonate (4.8 mg). The mixture was stirred at 60° C. for 3 hrs. The solution was then cooled down to room temperature. Water and TBDME were added. Organics were washed with water, dried over Na2SO4, filtered, concentrated under reduced pressure, and purified by silica gel chromatography to yield compound 307b as a white solid in 95% yield. 1H NMR (CDCl3, 400 MHz) δ (ppm) 4.11 (s, 3H), 6.71-6.72 (m, 2H), 7.54-8.05 (m, 5H), 8.58 (dd, J=2.78 Hz and J=1.00 Hz, 1H); 19F NMR (CDCl3, 376 MHz) δ (ppm) −62.45 (s, 3F).
