3,4-bis(benzyloxy)-6-[(E)-2-phenylvinyl]pyridazine → HCID 178515965, compound

Participants

Reaction Steps

To a solution (8 mL) of 3,4-bis(benzyloxy)-6-[(E)-2-phenylvinyl]pyridazine (272 mg) in ethanol was added 10% palladium-carbon (90 mg), and the mixture was stirred under a hydrogen atmosphere at room temperature for 4 hr. The catalyst was filtered off through celite, and the filtrate was concentrated under reduced pressure. To the residue was added ethyl acetate-chloroform, and the resulting solid was collected by filtration and dried under reduced pressure to give 3-hydroxy-6-(2-phenylethyl)pyridazin-4(1H)-one (60 mg).
