実験手順

To a stirred solution of (1S,2S,5S)-5-benzyl-2-[(4-phenylpiperazin-1-yl)carbonyl]-6-oxabicyclo[3.2.1]-octan-7-one (8.0 mg, 0.020 mmol) in anhydrous methanol (1.0 mL, 0.025 mol) at rt was added 1.50 M of hydroxylamine in methanol (0.396 mL). The reaction mixture was stirred at rt for 3 h. The reaction was quenched with saturated aqueous NH4Cl (15 mL), extracted with EtOAc (2×). The combined organic layers were washed with brine, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by reverse phase HPLC with 5-95% MeCN/H2O (with 0.05% TFA) to give the pure product as a colorless solid (2.3 mg, 26% in yield). MS (ESI): (M+H)+=438.1.
