Reaktionsschritte
To a solution of 2-(4-chloro-2-hydroxy-phenoxy)-1-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-ethanone (0.076 g, 0.18 mmol), triphenylphosphine (0.076 g, 0.29 mmol) and (2S)-2-hydroxy-propionic acid ethyl ester (0.036 g, 0.31 mmol) in tetrahydrofuran (1 mL) was added diethyl-azodicarboxylate (0.049 g, 0.29 mmol). The resulting mixture was stirred at ambient temperature overnight. The reaction was concentrated in-vacuo. Chromatography on silica gel gave the title compound (0.078 g)
