Procedure

To a solution of tert-butyl (6R,7S)-6-(3,4-dichlorophenyl)-7-(iodomethyl)-1,4-oxazepane-4-carboxylate (335 mg) in DMF (7.0 mL) were added 3(2H)-pyridazinone (79 mg) and potassium carbonate (143 mg), and the mixture was heated at 60° C. for 4 hr. The reaction solution was allowed to cool to room temperature, water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (2.49 g).
