Reaction Steps

To a solution of 4-fluorobenzaldehyde (1.5 g) and methylethylamine (1.56 mL) in dimethylsulfoxide (9 mL) was added potassium carbonate (2.17 g) and the mixture was stirred by using a microwave synthesizer (Biotage LTD.) at 120° C. for 2 hours. Thereto was added water and the mixture was extracted with ethyl acetate. The extract was dried over magnesium sulfate and concentrated in vacuo. The resultant crude product was purified by a column chromatography on silica gel (solvent; hexane/ethyl acetate=95:5→80:20) to give 4-(N-ethyl-N-methylamino)benzaldehyde (1.89 g, yield: 89%).
