Example 54 3 ‘-({ [(1 ,1-Dimethylethyl)(dimethyl)silyl] oxy} methyl)-5-fluoro- 3- biphenylcarbonitrile3-bromo-5-fluorobenzonitrile (5.00 g, 25.0 mmol), Pd(OAc)2 (0.15 g), PPh3 (0.60 g) and K2CO3 (5.18 g, 37.5 mmol) were dissolved in dioxane (60 mL). The mixture was heated at 700C for 30 min, then [3 -({[(l,l-dimethylethyl)(dimethyl)silyl] oxy} methyl) phenyljboronic acid (7.99 g, 30.0 mmol) was added. The mixture reaction was stirred at reflux overnight. The solvent was removed under reduced pressure, then diluted with CH2Cl2 (100 mL). The organic layer was washed with water (50 mL) and brine (50 mL). And the organic layer was dried over Na2SOzI. The product 3’-({[(l,l-dimethylethyl) (dimethyl)silyl]oxy} methyl)-5-fluoro-3-biphenylcarbonitrile (5.10 g, 60%) was purified by flash column chomatography. 1H NMR (400 MHz, CDCl3) delta 7.67 (t, J=5.2 Hz, 1 H), 7.54-7.32 (m, 5 H), 4.81 (s, 2 H), 0.94 (s, 9 H), 0.13 (s, 6 H).
