Toluene → 2-(4-Bromo-3-fluoro-phenyl)-pyrimidine

Participants

Reaction Steps

4-Bromo-3-fluorophenyl boronic acid (28AB) (1.0 g, 4.57 mmol, 1 equiv), 2-bromopyrimidine (1AB) (2.18 g, 13.7 mmol, 3 equiv), and 2M sodium carbonate (12 mL) were added in a pressure vessel (150 mL) and a (1v:1v) mixture of toluene and ethanol (25 mL: 25 mL) was added. The mixture was then bubbled with nitrogen gas for about 10 minutes. Tetrakistriphenylphosphine palladium (0) (266 mg, 0.23 mmol, 0.05 equiv) was added to the mixture. The reaction vessel was tightly capped, placed in an oil bath at 90° C., and stirred overnight.
