Reaction Steps
To a solution of (E1) and cesium carbonate (1.5 eq.) in DMF (0.25 M) at RT was added methyl iodide (1.0 eq.). After the mixture was stirred for 18 h, brine was added and the mixture was extracted with EtOAc. The organic phase was dried (Na2SO4) and concentrated under reduced pressure. The yellow solid was used in the next step without purification. 1H NMR (400 MHz, DMSO, 300K) δ 7.63 (2H, m), 3.83 (3H, s), 2.29 (3H, s).
