Reaction Steps
Tetrakis(triphenylphosphine)palladium (1 g) was added to a mixture of 5 g of 4-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 heated to refulux for 2 hours, concentrated, and the residue extracted twice with ethyl acetate. The ethyl acetate layer was washed with water, brine, dried, and concentrated to give a brown oily solid. The solid was chromatographed on silica gel in 5% ethyl acetate in hexane to give crude 4-fluoro-4′-methoxy-3-nitrobiphenyl as a pale yellow solid.
