Vorschrift

To a solution of compound 25 (1.32 g, 5.30 mmol) in methanol (10 mL) under argon was added palladium hydroxide (20%) on activated charcoal (132 mg, 10% w/w). The solution was purged three times with hydrogen and stirred under hydrogen atmosphere at 60° C. for 4 hrs. The resulting solution was then filtered on celite plug to give desired compound 26 (790 mg, 94%) which was used as such for the next step.
