Combine trifluoromethanesulfonic acid 6-hydroxy-1-[4-(2-piperidin-1-yl-ethoxy)-phenoxy]-naphthalen-2-yl ester (247 mg, 0.48 mmol), triphenylphosphine (190 mg, 0.725 mmol), benzyl alcohol (0.075 mL, 0.725 mmol) and tetrahydrofuran (5 mL) in a flask placed in an ice bath. Add diisopropyl azodicarboxylate (0.14 mL, 0.725 mmol), stir for 1 hour, warm to ambient temperature and stir for 30 minutes. Dilute with ethyl acetate and wash with 50% saturated aqueous sodium bicarbonate, saturated aqueous sodium chloride, dry with magnesium sulfate and remove solvent under vacuum. Chromatograph on silica gel with dichloromethane/methanol mixtures to give 213 mg of the title compound (73%).
