Versuchsvorschrift
A mixture of 43.0 mg (0.133 mmol) of compound 21 and 154.6 mg (2.36 mmol) of Zn in MeOH (10 mL) was stirred at room temperature for 75 hours under a N2 atmosphere. Zn was removed by filtration and washed thoroughly with MeOH. The combined organic layer was evaporated to yield 37.5 mg (0.133 mmol, 100% yield) of compound 22. MS (ES, positive) 282.7, 284.7.
