Reaction Steps

To a suspension of (5S)-5-((1S)-1-{[(2R)-4-(4′-fluorobiphenyl-4-yl)-2-methylpiperazin-1-yl]carbonyl}-3-methylbutyl)-2,2-dimethyl-1,3-dioxolan-4-one (230 mg, 0.48 mmol, 1.0 eq) in a mixture of iPrOH (4 mL) and THF (4 mL) was added a 50% aq. solution hydroxylamine (0.08 mL, 1.43 mmol, 3.0 eq). The reaction mixture was stirred at rt for 8 h. Evaporation of the solvent gave a white solid. This product was washed with iPr2O (2×), filtered and dried under vacuum to give the title compound as a white powder (89%). M−(EST): 456.3; M+(ESI): 458.4. HPLC (Condition A), Rt: 3.9 min (HPLC purity: 97.5%).
