Reaction Steps

To a stirred solution of 4-hydroxy-piperidine-1-carboxylic acid tert-butyl ester (0.49 mmol, 0.1 g) in THF (1.5 mL) at room temperature was added NaH (50 mg) followed 4-(4-benzyloxy-phenyl)-6-chloro-3-propyl-pyridazine (0.44 mmol, 0.15 g). The mixture was stirred at 70° C. for 4 h. The reaction mixture was cooled to room temperature, quenched with methanol by drop-wise addition, and removed the volatiles under reduced pressure. The residue was purified by flash silica gel column chromatography by eluting with 20% ethyl acetate to provide 4-[5-(4-benzyloxy-phenyl)-6-propyl-pyridazin-3-yloxy]-piperidine-1-carboxylic acid tert-butyl ester.
