Reaction Steps

To a solution of 554 μL (5.0 mmol) of 3,4-difluoronitrobenzene in 10 mL of dimethyl sulfoxide were added 1.38 mg (10.0 mmol) of potassium carbonate and 803 μL (10.0 mmol) of 2-methylaminoetanol, and the mixture was stirred for 1.5 hours at 100° C. The reaction mixture was cooled to room temperature and extracted with ethyl acetate, then, the extract was washed with water and saturated saline solution. After dried over with anhydrous sodium sulfate, the solvent was removed under reduced pressure ant the residue was purified by silica gel column chromatography (eluent:hexane/ethyl acetate=1/1) to give 1.06 g (99%) of the title compound.
