Versuchsvorschrift

To a solution of 1-[4-(4-fluoro-benzyl)-(2R)-2-methyl-piperazin-1-yl]-2-hydroxy-ethanone (0.77 g, 2.9 mmol) in dry toluene (30 mL) at 0° C. was added sodium hydride (0.13 g, 3.2 mmol, 60% dispersion in mineral oil). The reaction was stirred for 30 minutes at 0° C. followed by addition of 2,5-dichloro-3-nitro-pyridine (0.60 g, 3.18 mmol) as a solution in toluene (5 mL). The reaction was stirred at ambient temperature overnight. The, reaction was concentrated and chromatographed on silica gel to give the title compound (0.96 g).
