Versuchsvorschrift

A 100 ml flask was charged with 1-fluoro-4-nitrobenzene (2.122 ml, 20 mmol), dimethylsulfoxide (30 ml), N,N-dimethylpiperidin-4-amine (2.82 g, 22.00 mmol) and triethylamine (5.58 ml, 40.0 mmol). The resulting solution was stirred at 100° C. under nitrogen for 24 hours. The reaction mixture was allowed to cool, and was poured in stirring cold water (1000 ml) and the solid collected by filtration and washed with water. The precipitate was vacuum dried to provide the title compound. MS (ESI(+)) m/e 249.9 (M+H)+.
