Versuchsvorschrift

Compound 8 (4.24 g, 9.66 mmol), 2,3-dichloro-5,6-dicyano-4-benzoquinone (4.38 g, 19.3 mmol), and acetonitrile (100 mL) were combined and stirred at room temperature under argon for 24 h. The solvent was removed in vacuo and 5% ammonium hydroxide was added. The solution was extracted exhaustively with methylene chloride. The combined organic extracts were dried over anhydrous sodium sulfate and the solvent was removed in vacuo to give a solid. Trituration with hexane-ether gave Compound 9 as a solid: 3.5 g (8.0 mmol, 82%)
