Participants

Reaction Steps

A 500 ml three-necked flask equipped with stirrer, thermometer and reflux condenser was charged with 5-(p-methoxyphenyl)-2-furaldehyde oxime (28 g, 0.129 mole) and acetic anhydride (317 ml). This mixture was refluxed (138°) for 3 hours. After cooling to room temperature overnight, the green solution was poured into ice water (ca. 2l. ) with stirring. When the ice melted, the solid was collected by filtration, washed with water, and dried to give 26 g.
