Ethanol heptane → HCID 178518822, compound

Participants

Reaction Steps

3,4-bis(benzyloxy)-6-{[5-(trifluoromethyl)pyridin-2-yl]ethynyl}pyridazine (Intermediate 6; 460 mg, 0.997 mmol) was dissolved in ethanol and palladium on carbon was added before the mixture was purged and subjected to hydrogen gas. On completion of the reaction the solvent was removed in vacuo to yield a residue which was purified by reverse phase chromatography using 5-90% acetonitrile in acidic water (0.05% trifluoroacetic acid) to give, after recrystallisation from an ethanol-heptane mixture, 4-hydroxy-6-(2-(5-(trifluoromethyl)pyridin-2-yl)ethyl)pyridazin-3(2H)-one (136 mg, 0.48 mmol, 48% yield).
