To nitro-acetic acid ethyl ester (0.32 g, 2.39 mmol), sodium bicarbonate (0.10 g, 1.19 mmol) and tetrabutyl ammonium iodide (0.088 g, 0.24 mmol) in dimethyl formamide (5 ml) was added 2-(4-chloro-2-chloromethyl-phenoxy)-1-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-ethanone (0.52 g, 1.19 mmol). After 1 hour of heating at 60° C. the reaction was concentrated and then diluted with methylene chloride. After washing with aqueous saturated sodium bicarbonate and saturated sodium chloride the organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo. Chromatography on silica gel gave the title compound (0.30 g).
