To a stirred mixture of 2-(4-bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.120 g, 0.4 mmol) and potassium carbonate (0.056 g, 0.4 mmol) in DMF (3 mL) was added N-acetylpiperazine (0.052 g, 0.4 mmol) and the resulting reaction mixture stirred at room temperature for 2 hours. The solvent was removed in vacuo. The residue was suspended in MeOH and purified by SPE using an MP-TsOH resin (1000 mg) cartridge to afford 4-((4-acetylpiperazin-1-yl)methyl)phenylboronic acid as an oil which was used without further purification. LCMS (1) Rt: 1.04 min; m/z (ES+) 263.
