Versuchsvorschrift

A suspension of 4.97 g (19.6 mmole) of 2-bromo-6-phenylcyclohexanone in 120 mL of di-n-butyl ether was heated at 175° C. for 7 hours, at which point evolution of gaseous HBr had essentially ceased. The mixture was concentrated in vacuo and the residue purified by flash chromatography with 75:25 methylene chloride: hexanes to provide 2.69 g (80%) of a white solid.
