Reaction Steps

A mixture of 3-nitrobenzeneboronic acid (0.70 g, 4.2 mmol), 4-bromo-2-Fluoroaniline (730 mg, 4.0 mmol), (PPh3)4Pd (93 mg, 0.08 mmol), and K2CO3 (0.69 g, 5.0 mmol) in toluene (20 mL) and water (2 mL) was heated at 95° C. for 16 h and the mixture was diluted with EtOAc (20 mL). The mixture was washed with water (10 mL) and brine (10 mL), concentrated and purified by silica gel chromatography to afford the 4-amino-3-Fluoro-3′-nitrobiphenyl (structure 82 of Scheme XXI, where R1═R3-7=H, R8=F) (0.4 g, 41%) as a yellow solid.
