Versuchsvorschrift

Acetonitrile (30 mL) solution of 2 g of 2-methyl-4-nitrophenol, 1.87 g of 2-dimethylaminoethyl chloride and 5.4 g of potassium carbonate was stirred at 120° C. for 23 hours. The reaction liquid was concentrated under reduced pressure, and the residue was dissolved in ethyl acetate. The organic layer was washed with water, and dried with anhydrous sodium sulfate. The solvent was evaporated away under reduced pressure, and the crude product was purified through silica gel column chromatography (chloroform/methanol) to obtain 600 mg of the entitled compound as a white solid.
