Versuchsvorschrift

A solution of 4-(3-aminophenyl)pyridine (0.81 g) and 3-n-butoxy-3-cyclobutene-1,2-dione (0.73 g) in ethanol (20 ml) is stirred at ambient temperature for 15 hours. The resultant precipitated solid is washed with methanol and ether and recrystallized from dimethyl formamide to give 0.91 g of the title compound, mp 252-255.5° C.
