実験手順

Under ice-cooling, sodium hydride (60% in oil, 53 mg) was added to a solution of tert-butyl (6RS,7SR)-7-(3,4-dichlorophenyl)-6-hydroxy-1,4-oxazepane-4-carboxylate (400 mg) in DMF (5 mL). After stirring at room temperature for 20 min, methyl 6-chloropicolinate (280 mg) and sodium iodide (330 mg) were added, and the mixture was stirred at the same temperature for 1 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (207 mg).
