Versuchsvorschrift

1-Fluoro-4-nitrobenzene (4.9 g, 34.75 mmol) was added to cis-2,6-dimethylmorpholine (44.4 g, 38.26 mmol) and anhydrous potassium carbonate (2.5 g, 18.12 mmol) in acetonitrile (50 ml). The reaction was heated under reflux for 19 hours, cooled, filtered and the solid washed with acetonitrile. Evaporation of the filtrate gave the title compound as a yellow solid. (8.1 g, 99%) NMR (CDCl3) 1.28 (d, 6H), 2.61 (t, 2H), 3.66 (td, 2H), 3.76 (m, 2H), 6.82 (d, 2H), 8.13 (d, 2H); m/z 237.
