Reaction Steps
To a solution of 1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl) piperazine hydrochloride (419 mg, 1.29 mmol) and cesiumcarbonate (1.27 g, 3.9 mmol) in THF (30 mL) was added acetyl chloride (0.5 mL, 6.5 mmol). Then the mixture was stirred at room temperature overnight, extracted with EA, washed with NaHCO3 solution and brine. The organic solution was concentrated and purified by flash column chromatography, eluting with PE/EA, to give product as a white solid. MS (m/z): 331 (M+H)+.
