Procedure

A mixture of 3-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxymethyl]-4,4-difluoro-piperidine-1-carboxylic acid tert-butyl ester (0.36 mmol, 0.2 g) and 4M HCl in dioxane solution (3 mL) in 10 mL of DCM was heated at 50° C. for 1 h. Removed the solvent afforded the crude 3-butyl-4-(4-cyclohexyloxy-phenyl)-6-(4,4-difluoro-piperidin-3-ylmethoxy)-pyridazine dihydrochloride as a yellowish solid.
