Reaction Steps

After adding 2,2,6,6-tetramethylpiperidine 1-oxyl free radical (32 mg, 0.20 mmol) to a solution of 4-[2-[1-(2-hydroxyethyl)cyclohexyl]ethyl]morpholine (439 mg, 1.82 mmol) and iodobenzene diacetate (644 mg, 2.00 mmol) in methylene chloride (10 mL), the mixture was stirred at room temperature for 14 hours. The reaction mixture was washed with saturated aqueous sodium hydrogencarbonate and saturated brine in that order and dried (anhydrous sodium sulfate), and then the solvent was distilled off under reduced pressure to obtain the title compound as a brown oil (625 mg). This was used without purification for the following step.
