5-Methyl-2-(3-(piperidin-4-ylidenemethyl)phenoxy)pyridine hydrochloride (507 mg, 1.6 mmol, from Example 44, Step 5), phenyl pyridazin-3-ylcarbamate (430 mg, 2.0 mmol) and triethylamine (0.892 mL, 6.4 mmol) were combined in acetonitrile (10 mL) and stirred at room temperature. After 16 h, the reaction was concentrated and the residue was partitioned between EtOAc and water. The organic layer was separated, dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified by silica gel chromatography (0-10%, MeOH:CH2Cl2) to afford the title compound (526 mg) as a foamy white solid.
