Reaction Steps

A mixture of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (0.120 g, 0.55 mmol), 1-(2-chloroethyl)piperidine hydrochloride (0.100 g, 0.54 mmol), potassium carbonate (0.226 g, 1.64 mmol) and 18-crown-6 (0.072 g, 0.27 mmol) in MeCN (3 mL) was heated in the microwave at 180° C. for 10 minutes. The mixture was diluted with MeOH and a small amount of water and purified by SPE using a MP-TsOH resin (1000 mg) cartridge. The solvent was removed in vacuo to afford 4-(2-(piperidin-1-yl)ethoxy)phenylboronic acid (0.129 g, 0.52 mmol, 95%) which was used without further purification. LCMS (1) Rt: 1.55; m/z (ES+) 250.
