실험 절차
The abovementioned mixture of ethyl 2-formyllevulinate and its diethyl ketal was dissolved in benzene, the catalyst was added, and the resulting solution was refluxed with a Dean-Stark trap for 3-3.5 h until the water was completely removed. The reaction mixture was then distilled under reduced pressure, resulting in 15 g (97 mmol) of ethyl 5-methylfuran-3-carboxylate, boiling point 97° C./15 mm Hg.
