実験手順

To a solution of (2-chloro-1-[4-(4-fluoro-benzyl)-2,5-dimethyl-piperazin-1-yl]-ethanone (0.10 g, 0.35 mmol) in 2-butanone (1 mL) was added potassium carbonate (0.13 g, 0.90 mmol), potassium iodide (0.065 g, 0.39 mmol) and 5-(5-chloro-2-hydroxy-phenyl)-5-oxo-pentanoic acid ethyl ester (0.11 g, 0.39 mmol). The reaction was stirred at 60° C. for 12 hours, then cooled and concentrated. Chromatography on silica gel gave the title compound (0.089 g).
