実験手順
A 1-liter 3-neck flask equipped with stirrer, condenser, heating mantle, addition funnel and thermometer is charged with 47 g (0.5 mole) of 4-aminopyridine and 66 g (0.5 mole) of 2,5-dimethoxytetrahydrofuran. These materials are mixed together and 210 ml of glacial acetic acid is added dropwise with stirring over ten minutes while maintaining the temperature at less than 20°C.
