Versuchsvorschrift
To a solution of the obtained methyl 5-(4-pyridyl)-2-furancarboxylate (100 mg) in ethanol (10 ml) was added 1 N sodium hydroxide solution (4 ml) and the solution was stirred at room temperature for 2 hours. The reaction solution was concentrated and the residue was dissolved in water, to which was added 1 N hydrochloric acid (4 ml). The precipitate was filtered, washed with water and dried to give the title compound (59 mg).
