Komponenten

Versuchsvorschrift

To a solution of tert-butyl (6RS)-6-(3,4-dichlorophenyl)-6-hydroxy-1,4-oxazepane-4-carboxylate (130 mg) in DMF (3.0 mL) were added 60% sodium hydride (44 mg) and methyl iodide (0.068 ml) at room temperature, and the mixture was stirred for 30 min. To the reaction mixture was added ice water, and the mixture was extracted with ethyl acetate. The extract was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (186 mg).
