実験手順

A mixture of 3-[2-(2-oxocyclohexyl)-3-oxo-2,3-dihydropyridazin-6-yl]-2-phenylpyrazolo[1,5-a]pyridine (231 mg), semicarbazide hydrochloride (101 mg), potassium carbonate (125 mg), water (2 ml), and ethanol (10 ml) was heated under reflux for 4 hours. Ethanol was evaporated in vacuo and the residue was partitioned between dichloromethane (30 ml) and saturated aqueous sodium bicarbonate (30 ml). After an additional extraction with dichloromethane, the combined extracts were washed with brine (20 ml), dried over anhydrous sodium sulfate, and evaporated in vacuo to give colorless crystals of 3-[2-(2-carbamoylhydrazonocyclohexyl)-3-oxo-2,3-dihydropyridazin-6-yl]-2-phenylpyrazolo[1,5-a]pyridine (125.8 mg).
