Reaction Steps

To 5-bromo-2-nitrophenyl methyl ether (8.0 g, 34.47 mmol) in 80 mL of n-propanol was added, PdCl2(dppf)*DCM (0.5 g, 0.69 mmol), potassium ethenyl(trifluoro)borate (6.47 g, 48.3 mmol), and TEA (3.48 g, 34.47 mmol). The mixture was heated to 100° C. for 3 h. The mixture was poured into 250 mL of H2O and extracted with DCM, dried (Na2SO4), filtered, and rotovaped down, and purified by flash chromatography to give the title compound of step B (3.58 g, 19.98 mmol, 58%). 1H NMR (400 MHz, CDCl3) δ ppm 7.82-7.87 (m, 1H), 7.02-7.07 (m, 2H), 6.70 (dd, J=17.58, 10.80 Hz, 1H), 5.87 (d, J=17.58 Hz, 1H), 5.46 (d, J=10.99 Hz, 1H), 3.97 (s, 3H).
