Reaction Steps
A mixture of 1,2-difluoro-4-nitrobenzene (1.0 g, 6.29 mmol), 2-morpholinoethanol (1.0 g, 7.62 mmol) and Cs2CO3 in DMF (10 mL) was stirred at 75° C. for 12 h. 30 mL of water was then added and the resulting mixture was extracted with DCM (30 mL×2). The combined organic phases were washed with brine (30 mL×3), dried over anhydrous Na2SO4 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 yellow oil (1.30 g, 76%).
