실험 절차
A solution of 3-(4-aminophenyl)pyridine (0.51 g) and 3-amino-4-ethoxy-3-cyclobutene 1,2-dione (0.42 g) in pyridine (2 ml) is stirred at 80° for 20 hours. The cool mixture is treated with water (15 ml), and the solid filtered off and washed with water and hot methanol. Recrystallation from dimethylformamide gives 0.33 g of the title compound, mp 3224° C. dec.
