Procedure

To a solution of 4-[6-cyclobutyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxy]-piperidine-1-carboxylic acid tert-butyl ester (0.35 mmol, 0.18 g) in DCM (1.0 mL) was added 4 N HCl in dioxane (1.0 mL) and the reaction was stirred for 30 min. The solvents were removed under reduced pressure and the residue was triturated with anhydrous ethyl ether and filtered to give 3-cyclobutyl-4-(4-cyclohexyloxy-phenyl)-6-(piperidin-4-yloxy)-pyridazine dihydrochloride (0.14 g).
