Procedure

A RBF was charged with 4-(benzylthio)-2-nitroaniline (1.80 g, 6.91 mmol), 4′-chloro-2-fluoro-4-iodo-5-methoxy-3′-methyl-1,1′-biphenyl (2.86 g, 7.61 mmol), xantphos (0.200 g, 0.346 mmol), Pd2(dba)3 (0.158 g, 0.173 mmol), CPME (13.83 ml) and cesium carbonate (3.15 g, 9.68 mmol). A reflux condenser was attached and the flask was lowered into a 110° C. heating for 3 hours. The mixture was cooled to room temperature, diluted with EtOAc, and filtered through celite with the aid of EtOAc. The filtrate was concentrated. The oily residue was purified using Biotage and eluting with 0-50% EtOAc/Heptane to give N-(4-(benzylthio)-2-nitrophenyl)-4′-chloro-2-fluoro-5-methoxy-3′-methyl-[1,1′-biphenyl]-4-amine (2.56 g, 5.03 mmol, 72.7% yield) as a bright-yellow solid. m/z (ESI) 509.1 (M+H)+.
