Participants

Reaction Steps

To a stirred solution of (±)-trans-3-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxymethyl]-4-(4-nitro-benzoyloxy)-piperidine-1-carboxylic acid tert-butyl ester (0.914 mmol, 0.63 g) in a mixture of methanol (8 mL) and water (2 mL) was added sodium hydroxide (0.3 g) and continued stirring for 3 h at room temperature. The volatiles were removed under reduced pressure and the residue was dissolved in water (20 mL). This was extracted with ethyl acetate (3×15 mL), combined organic layer was dried, filtered and concentrated. The residue was purified by flash silica gel column chromatography by eluting with 20% ethyl acetate in hexanes to provide (±)-trans-3-[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazin-3-yloxymethyl]-4-hydroxy-piperidine-1-carboxylic acid tert-butyl ester (0.395 g) as an white solid.
