Versuchsvorschrift
To 0.05 g (0.19 mmol) of the titled product of Example 8 is added 0.6 ml (0.22mmol) of tri-n-butyltin hydride, and 20 mg of azoisobutyronitrile (AIBN). The reaction mixture was heated at 110° C. for 3 hours, whereupon thin layer chromatography indicated that the reaction was complete, producing the titled product. The product was used without further purification.
