実験手順
To a solution of 3-(5-chloro-2-{2-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-2-oxo-ethoxy}-benzylamino)-propionic acid methyl ester (0.035 g, 0.069 mmol) in tetrahydrofuran (0.2 mL), methanol (0.2 mL) and water (0.1 mL) was added lithium hydroxide monohydrate (0.015 g, 0.35 mmol). The reaction mixture was stirred at ambient temperature overnight. The reaction mixture was then concentrated in vacuo and the resulting residue was dissolved in dichloromethane and treated with hydrogen chloride gas. The resulting white solid was washed with acetonitrile. The acetonitrile wash was concentrated to give the title compound as its hydrochloride salt (0.010 g, LRMS: 490.3).
