Participants

Reaction Steps

To a solution of tert-butyl (6R,7R)-6-{[(2-{[tert-butyl(dimethyl)silyl]oxy}ethyl)(pyrrolidin-1-ylacetyl)amino]methyl}-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (118 g) in THF (0.6 ml) was added, under ice-cooling, a solution (1.0 M, 0.219 ml) of tetrabutylammonium fluoride in THF, and the mixture was stirred at room temperature overnight. To the reaction mixture was added distilled water, and the mixture was extracted with ethyl acetate. The extract was washed with distilled water and brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (NH, hexane/ethyl acetate/methanol) to give the title compound (81.3 mg).
