A solution of the obtained 7-oxoazepane-4-carboxylate (2.02 g) in THF (29 mL) was added dropwise to a suspension of lithium aluminum hydride (2.07 g) in THF (80 mL) under ice-cooling. The reaction mixture was stirred at room temperature for 3 hr and at 60° C. overnight. The reaction mixture was ice-cooled, diluted with THF (200 mL), and water (2.02 mL) was slowly added dropwise. Furthermore, 15% aqueous sodium hydroxide solution (2.02 mL) was added dropwise, then water (4.04 mL) was added, and the mixture was stirred at room temperature for 3 hr. The solid was separated by filtration, and the filtrate was concentrated under reduced pressure to give the title compound (1.41 g).
