실험 절차
(±)-cis-6-Butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carboxylic acid (3-fluoro-1-methyl-piperidin-4-ylmethyl)-amide (0.35 mmol, 160 mg) was stirred in 4 M HCl/dioxane (1 mL) for 20 min at room temperature. After evaporating the solvent, dichloromethane (0.2 mL) and hexane (1 mL) was added to precipitate (±)-cis-6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carboxylic acid (3-fluoro-1-methyl-piperidin-4-ylmethyl)-amide dihydrochloride.
