Procedure

To a stirred solution of (±)-trans-3-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxymethyl]-4-hydroxy-piperidine-1-carboxylic acid tert-butyl ester (0.157 mmol, 0.85 g; Example 46) in DCM (1 mL) was added 4 N HCl in dioxane (4 mL) and continued stirring for 30 min at room temperature. The volatiles were removed under reduced pressure. The residue was washed with anhydrous ether and the solid was dried under high vacuum to provide (±)-trans-3-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxymethyl]-piperidin-4-ol.
