Reaction Conditions

Reaction Steps

Anhydrous toluene was sparged with argon gas for 1 h before being used. Palladium acetate (0.050 g, 0.22 mmol), triphenylphosphine (0.255 g, 0.973 mmol), cesium carbonate (1.87 g, 5.75 mmol) and 3-bromo-5-trifluoromethyl-pyridine (1.00 g, 4.42 mmol) were introduced into a 50 mL round bottom flask under argon. Toluene (10 mL) and triisopropylsilanethiol (1.23 mL, 5.75 mmol) were added. The reaction was stirred at 100° C. overnight, then cooled to room temperature and diluted with hexanes. The suspension was filtered through a plug of Celite. The filtrate was concentrated to afford 3-trifluoromethyl-5-triisopropylsilanylsulfanyl-pyridine which was used in the next reaction step without further purification.
