Participants

Reaction Steps

Lithium aluminum hydride (90 mg) was added to a solution of aluminum chloride (90 mg) in THF (5 mL), and the mixture was stirred at room temperature for 40 min. A solution of tert-butyl (6SR,7SR)-6-(3,4-dichlorophenyl)-7-[(2-ethoxy-2-oxoethoxy)methyl]-1,4-oxazepane-4-carboxylate (300 mg) in THF (5 ml) was added dropwise to the reaction mixture, and the mixture was stirred at 0° C. for 1 hr. Sodium sulfate 10 hydrate was added to the reaction mixture, the mixture was stirred at room temperature for 30 min, and the resultant salt was filtered off. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give the title compound (200 mg).
