Vorschrift

A mixture of regioisomeric olefins 54 (100 mg, 0.42 mmol) and Pd 10% on C (10 mg) in methanol (4 mL) was vigorously stirred under H2 atmosphere (14 psi). The mixture was stirred for 2 hours at room temperature, filtered through Celite and evaporated to afford 55 as an oil. Flash chromatography of the residue gave 55 (88 mg, 88%).
