Versuchsvorschrift
A suspension of 2-morpholinoethanamine (5.34 g, 41 mmol), 2,4-dichloro-1-nitrobenzene (7.87 g, 41 mmol) and Cs2CO3 (26.73 g, 82 mmol) in acetonitrile (100 mL) was refluxed for 6 h under N2, then cooled to rt, filtered and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=4:1) to give the title compound as a yellow solid (5.90 g, 50%).
