After the formation of a white solid, the reaction is monitored (TLC) until complete disappearance of the triazine. 1-Phenyl-2-(1-phenylethylidene)-hydrazine (1.0 g, 5.0 mmol) in DMF (15 mL) is added. After the addition, the mixture is then stirred at room temperature and monitored for completion (TLC) after which a 15% solution of Na2CO3 (20 mL) is added. The organic phase is extracted twice with 15 mL of diethyl ether. The organic layer is then dried (Na2SO4) and the solvent is removed in vacuo to afford the desired product. Yields of approximately 1.12 g (90%) of this product can be expected when the reaction is conducted on this scale. Mp 145° C.
