To a solution of (1,9-Dihydro-1,3,4,9-tetraaza-fluoren-2-ylidene)-hydrazine 14d (27 mmol, 1 equiv.) in ethanol (50 mL) is added 2-pyridinecarboxaldehyde (27 mmol, 1 equiv.). The mixture is heated at 60° C. for 10 hours. The solution is allowed to cool to room temperature. The product is filtered and dried under vacuum for 15 hours. N-Pyridin-2-ylmethylene-N′-(9H-1,3,4,9-tetraaza-fluoren-2-yl)-hydrazine 14e is obtained as a pale yellow solid.
