The synthetic route is as follows., 156682-52-9
1,4-dibromo-2,3-difluorobenzene (15 g, 55.2 mmol), (2-methoxyphenyl)boronic acid (8.80 g, 57.9 mmol), sodium carbonate (11.69 g, 110 mmol), and tetrakis(triphenylphosphine)palladium(0) (3.19 g, 2.76 mmol) were dissolved in a mixture of water (140 ml) and dioxane (140 ml). The reaction mixture was degassed and heated in an 80 C. oil bath for 20 h. The reaction mixture was cooled to room temperature, mixed with brine and extracted with EtOAc. The extract was washed with water, brine, dried, and evaporated to leave a solid/liquid mixture that was absorbed onto a silica gel plug and chromatographed on silica gel column eluted with heptane to yield 4-bromo-2,3-difluoro-2?-methoxy-1,1?-biphenyl as a colorless oil (12.5 g, 75% yield).
