Reaction Steps

To a solution of 4-(4-benzyloxy-3-methoxy-phenyl)-3-butyl-6-(1-methyl-piperidin-4-yloxy)-pyridazine (1.0 mmol, 462 mg) in methanol/ethyl acetate (10 mL, 1/1) was added 10% palladium on activated carbon (70 mg). The mixture was repeatedly de-gassed under vacuum, filled with hydrogen for 3 times. Then hydrogen balloons were attached to the reaction, which was stirred at room temperature for 2 hours. TLC/LCMS monitored to completion. The mixture was then filtered through celite, the celite cake was washed with 1/1 methanol/ethyl acetate for 3 times, and the organic layers were combined and condensed under reduced pressure to give 4-[3-butyl-6-(1-methyl-piperidin-4-yloxy)-pyridazin-4-yl]-2-methoxy-phenol as a white powder (327 mg), which was used directly in the next step.
