Procedure

To a stirring solution of 4-[6-butyl-5-(3-cyano-4-cyclohexyloxy-phenyl)-pyridazin-3-yloxy]-piperidine-1-carboxylic acid tert-butyl ester (0.025 g, 0.046 mmol) in DCM (2.0 mL), 4.0 M HCl in dioxane (2.0 mL) was added and stirring continued for 30 min. Solvent evaporated, resulting solid was washed with ether, dried to get 5-[3-Butyl-6-(piperidin-4-yloxy)-pyridazin-4-yl]-2-cyclohexyloxy-benzonitrile dihydrochloride (22 mg).
