Participants

Reaction Steps

To a 1000 mL, 3-necked flask equipped with a stir bar, nitrogen inlet, and a reflux condenser were added 2,5-dibromopyridine (39.9 g, 84.2 mmol), 3-biphenylboronic acid (20.0 g, 101 mmol), palladium(II) acetate (0.47 g, 2.1 mmol), triphenylphosphine (2.2 g, 8.4 mmol), sodium carbonate (24.1 g, 227 mmol), dimethoxyethane (170 mL), and water (114 mL). The reaction mixture was heated at reflux for 16 h, after which ethyl acetate (200 mL) was added. The organic layer was then dried over magnesium sulfate and evaporated to dryness. Purification of the resulting solid on a silica gel column with ethyl acetate/hexane as the eluent yielded 19.0 g (73%) of 2-(biphenyl-3-yl)-5-bromopyridine as a white solid.
