Reaction Conditions

Reaction Steps

A flask is charged with 4-bromo-2-iodo-phenylamine (1.10 g, 3.70 mmol), 4,4-dimethylcyclohexen-1-ylboronic acid (0.630 g, 4.07 mmol), Pd(PPh3)4 (0.240 g, 5 mol %), 2 M Na2CO3 (16 mL), EtOH (16 mL) and toluene (32 mL) and heated at 80° C. for 6 h. The reaction was diluted with EtOAc (100 mL) and washed with saturated aqueous NaHCO3 (2×100 mL) and brine (100 mL), and the organic layer dried over Na2SO4 and evaporated. The crude product was purified by flash silica gel chromatography eluting with 10% EtOAc/hexane to give 0.68 g (66%) of the title compound as a light yellow oil: Mass spectrum (ESI, m/z) calcd. for C14H18BrN, 280.1 (M+H), found 280.1.
