Reaction Conditions

Reaction Steps

The nitrile 25C (2.0 g, 11.1 mmol), 4-trifluoromethylphenylboronic acid (2.32 g, 1.1 mol eq), palladium acetate (50 mg, 0.02 mol eq), cesium carbonate (7.23 g, 2 mol eq), and XPhos (210 mg, 0.04 mol eq) were mixed, placed under a nitrogen atmosphere and dioxane (10 mL) was added. The mixture was heated at 100° C. for 3 h. After cooling, the mixture was filtered through a celite pad, washed with dioxane (2×20 mL) and concentrated under reduced pressure. The residue was purified by flash chromatography (9.5/0.5 petroleum ether/EtOAc) to afford 26E as a pale yellow solid (2.2 g, 68% Yield). 1HNMR (DMSO, 200 MHz) δ 3.13 (s, 6H), 7.12 (s, 1H), 7.58 (s, 1H), 7.82 (d, 2H, J=7.7), 8.30 (d, 2H, J=7.8).
