실험 절차

To a solution of 5-(5-chloro-2-{2-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-2-oxo-ethoxy}-phenyl)-5-oxo-pentanoic acid ethyl ester (0.089 g, 0.17 mmol) in 2:2:1 tetrahydrofuran:methanol:H2O (2 mL) was added lithium hydroxide hydrate (0.025 g, 0.60 mmol). The reaction was stirred at ambient temperature for 4 hours. The pH was then adjusted to 4 with 0.2 M hydrochloric acid. The solution was extracted with ethyl acetate and the organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo. Anion exchange chromatography (MCX) provided the title compound (0.014 g, LRMS: 505.5, 507.5).
