Sodium Carbonate → 4-Fluoro-2'-methoxy-3-nitrobiphenyl

関与物質

反応手順

Tetrakis(triphenylphosphine)palladium (1 g) was added to a mixture of 5 g of 2-methoxyphenylboronic acid, 6.6 g of 5-bromo-2-fluoronitrobenzene and 30 mL of 2 M sodium carbonate solution in 50 mL of toluene and 50 mL of ethanol. The mixture was refluxed for 2 hours, concentrated, and the residue extracted twice with ethyl acetate. The ethyl acetate layer was washed with water and brine, dried, and concentrated to give a dark green oil which solidified on standing to give crude 4-fluoro-2′-methoxy-3-nitrobiphenyl.
