実験手順

5-Bromofuraldehyde was dissolved in dimethylsulfoxide (DMSO) and 1-2 drops of Aliquart 336 (tricaprylylmethylammonium chloride, produced by Aldrich Co.) was added to the solution. 10 Equivalents diethylamine was added to the mixture and refluxed for 4 days. The remaining diethylamine was removed from the reaction mixture and subjected to extraction and column chromatography to obtain 5-diethylamino-2-furaldehyde with a yield of 85%.
