実験手順

A solution of Example 87B (7.28 g, 20.72 mmol) in methyl cyclohexane (1.5 L) was degassed with nitrogen and (1,3-bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium (250 mg, 0.294 mmol) was added. The mixture was stirred at room temperature overnight and diethyleneglycol vinyl ether (0.16 mL) was added to inactivate any remaining active catalyst. The mixture was stirred for 30 minutes, concentrated and purified by flash chromatography on silica using an Analogix system (0-10% ethyl acetate/heptane) to provide the title compound. MS (ESI+) m/z 346 (M+Na)+.
