YieldReaction ConditionsOperation in experiment
56% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In N,N-dimethyl-formamide; at 120℃; for 14h;Inert atmosphere; Sealed tube; A solution of 4-(trifluoromethyl)phenylboronic acid (519 mg, 2.73 mmol), <strong>[10386-27-3]2-bromo-isonicotinonitrile</strong> (500 mg, 2.73 mmol) and potassium carbonate (358 mg, 2.73 mmol) in DMF (5 mL) at 25°C was purged with nitrogen gas and evacuated three times. The solution was then treated with tetrakis(triphenylphosphine)palladium(0) (158 mg, 137 tmol) and then sealed and heated to 120°C for 14 h. The reaction mixture was cooled to 25°C, unsealed and poured into water. The aqueous phase was extracted three times with ethyl acetate. The combined organic layers were washed with brine and dried over magnesium sulfate. Filtration followed by concentration in vacuo gave a brown solid. Flash chromatography (80/20 hexanes/ethyl acetate) afforded 2-(4-trifluoromethyl-phenyl)- isonicotinonitrile (0.38 g, 56percent) as a white solid. MH+ = 248.9
