Procedure
In 10 ml of toluene was dissolved 3.0 g (15.9 mmol) of ethyl 5-chloromethyl-2-furancarboxylate, followed by addition of 10 ml (71.5 mmol) of diisopropylamine. The mixture was heated at 100° C. for 48 hours. After cooling, the reaction mixture was filtered to remove the precipitate and the filtrate was concentrated under reduced pressure. The residue was then purified by silica gel column chromatography (chloroform-methanol =20:1) to give 2.26 g (56.1%) of ethyl 5-diisopropylaminomethyl-2-furancarboxylate (Compound f) as light tan-colored oil.
