Reaction Steps

To a stirred solution of 1-(4-methoxybenzyl)piperidin-4-ol (0.33 g, 1.49 mmol) in toluene (10 mL) at room temperature was added triphenylphosphine (0.44 g, 1.67 mmol) and methyl 3-chloro-4-hydroxybenzoate (0.42 g, 2.25 mmol). The reaction was stirred at room temperature for 5 min. After this time, diisopropyl azodicarboxylate (0.33 g, 1.67 mmol) was added dropwise and the reaction was stirred at room temperature overnight. The mixture was concentrated under reduced pressure and the resulting residue was purified by flash chromatography (silica gel, methylene chloride/methanol/30% ammonium hydroxide=25/1/0.05) to afford methyl 3-chloro-4-(1-(4-methoxybenzyl)piperidin-4-yloxy)benzoate as a white solid (0.05 g, 10%). MS (ESI): 390.1 (M+1).
