Procedure

To a stirred solution of (±)-cis-3-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxymethyl]-4-hydroxy-piperidine-1-carboxylic acid tert-butyl ester (0.37 mmol, 0.2 g) in DCM (2 mL) was added 4 N HCl in dioxane (4 mL) and continued stirring for 1 h at room temperature. The volatiles were removed under reduced pressure; residue was dissolved in DCM, added hexanes to precipitate the desired HCl salt. Solvent was removed under reduced pressure and the solid was dried under high vacuum to provide (±)-cis-3-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxymethyl]-piperidin-4-ol.
