Procedure

A round bottom flask was charged with (S)-2-(4-benzylpiperazin-2-yl)ethanol (1.0 g, 4.5 mmol), 2-bromo-5-methoxyphenol (1.0 g, 5.0 mmol), di-tert-butyl azodicarboxylate (1.57 g, 6.81 mmol), polymer-supported triphenylphosphine resin (4.354 g, 9.08 mmol) and tetrahydrofuran (30 mL). The reaction stirred for 16 hours. The resin was removed via filtration and the solution was concentrated. Purification via flash chromatography (0-30% methanol/dichloromethane) afforded the title compound.
