To a solution of 3-nitrobenzyl bromide (10.5 g, 48.7 mmol) in methylene chloride is added azepane (5.5 mL, 48.7 mmol) and 20.0 mL (146.1 mmol) of triethylamine, and the reaction solution is heated at 60□C under N2 for 20 minutes. After evaporating to dryness, the resulting brown residue is dissolved in methylene chloride and washed twice with saturated Na2CO3 solution, and once with brine solution. After drying over Mg2SO4, the organic solution is filtered and concentrated to give 8.0 g (70.1% yield) of brown oil.
