실험 절차

1-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl)-4-methylpiperazine was prepared by reacting 2-(3-(bromomethyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (100 mg, 0.35 mmol) with methyl piperazine (196 μl, 1.76 mmol) in THF at room temperature for 2 hours. The intermediate product was purified by flash chromatography to afford 68 mg of colorless oil.
