Reaction Steps

Mix propane-2-sulfonic acid{2-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-thiophen-3-yl}-amide (0.10 g), 0.1 equiv of tetrakis triphenylphosphine palladium (0), 2 equiv of 2M sodium carbonate aqueous solution in DME (2 mL) and EtOH(1 mL) and warm to 90-95° C. After warming two min, add 2-(4-bromo-phenyl)-ethanol (1.3 equiv) and stir at that temperature for 1.5 h. Evaporate solvents over Celite® and purify by silica gel Strata® cartridges eluting with hexanes-EtOAc gradient to give 0.041 g of the title compound. MS (ES+) (m/z): 402 (M+1).
