Reaction Steps
A solution of diethylstyrylamine (1.75 g) in acetic anhydride (5 ml) was heated under reflux for an hour and then distilled under vacuum (0.02 mm) in a bulb-to-bulb apparatus (oven 150° C.). The product was crystallised from ether-petroleum spirit (40°-60° C.) at low temperature, giving crystals of the title product which melted around room temperature.
