Reaction Steps
A mixture of (±)-trans-4-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxy]-3-fluoro-piperidine-1-carboxylic acid benzyl ester (65 mg, 0.12 mmol) and 10% palladium on carbon (10 mg) in MeOH (5 mL) was stirred under an atmosphere of H2 for 1.5 hrs, filtered through celite and concentrated to provide (±)-trans-3-butyl-4-(4-cyclohexyloxy-phenyl)-6-(3-fluoro-piperidin-4-yloxy)-pyridazine (40 mg).
