실험 절차

A solution of (5R)-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-3-{6-[2-({4-[(diphenylmethylene)amino]benzyl}oxy)ethoxy]hexyl}-1,3-oxazolidin-2-one (860 mg) in MeOH (13 ml) was treated with sodium acetate (255 mg) followed by hydroxylamine hydrochloride (162 mg) and the mixture was stirred at 20° for 0.5 h. Phosphate buffer solution (30 ml, pH6.5) was added and the mixture was extracted with EtOAc. The combined extracts were dried (Na2SO4) and the solvent evaporated in vacuo. The residue was purified by SPE (silica, 10 g). Elution with EtOAc-cyclohexane (1:1) then (4:1) gave the title compound (321 mg). LCMS RT=3.18 min.
