With 1,1'-carbonyldiimidazole; In tetrahydrofuran; water; EXAMPLE 6 p-Formyl-N,N-dimethylbenzamide benzylamidinohydrazone hydrochloride A mixture of 15.0 g. of 4-carboxybenzaldehyde, 17.0 g. of N,N'-carbonyldiimidazole and 150 ml. of tetrahydrofuran is allowed to stand at room temperature for one hour. Dimethylamine is passed thru the above solution for one hour and the reaction mixture is allowed to stand at room temperature for 18 hours, then is heated at reflux temperature for one hour. Water is added and the solvent is distilled off. The residue is extracted with methylenechloride. The organic layer is washed with dilute hydrochloric acid and water, dried over magnesium sulfate and concentrated to an oil. The oil is triturated with a little methylene chloride and the insoluble material is filtered off. The mother liquor is concentrated and 7.9 g. of p-formyl-N,N-dimethylbenzamide is obtained as an oil.

YieldReaction ConditionsOperation in experiment
In ethanol; at 60℃; for 0.5h; General procedure: A mixture of corresponding hydrazinylpyridazine 1 or 5 (1 mmol) and aldehyde 2 (1.1 mmol) in ethanol (5 mL) was heated at 60 oC for 0.5 h. The formation of hydrazone was checked by TLC and the reaction mixture was cooled to rt. Oxone (1.5 mmol) was added to the mixture at rt followed by tetramethyl ammonium bromide (0.2 mmol) and the resulting mixture was heated at 60 oC for another 5 h. The mixture was cooled to rt and extracted with dichloromethane (2 × 25 mL), dried over anhydrous sodium sulphate and concentrated to obtain a residue which was purified by column chromatography using hexane/ethyl acetate as eluent to furnish the desired triazolopyridazines 4 and 7.
