Reaction Steps

The mixture of 3,4-difluorophenylboronic acid (0.083 g, 0.527 mmol), sodium carbonate (0.406 mL, 0.813 mmol), (E)-9-(triisopropylsilyloxy)-8,9-dihydro-7H-cyclohepta[b]pyridin-6-yl trifluoromethanesulfonate (0.2045 g, 0.439 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.025 g, 0.022 mmol) in Toluene (5 mL) and MeOH (1 mL) was heat to 80° C. under N2 for 3 hours. LCMS showed no more starting material. The reaction was diluted with ethyl acetate and washed with water one time. The ethyl acetate layer was separated, dried (Na2SO4), filtered and concentrated to give the crude product. The Crude was used as it is. MS(ESI)[M+H+]=430.36.
