To a Schlenk flask charged with Grubbs? catalyst 2 (0.42g, 0.50mmol) and CuCl (0.05g, 0.50mmol), compound 9 (0.6mmol) in 10mL dry dichloromethane was added at room temperature under N2. The resulting mixture was stirred for 40min at 40C. After being cooled to room temperature, the reaction mixture was filtered and the clear filtrate was collected. The solvent from the filtrate was evaporated under vacuum to give a residue. The residue was purified by silica gel chromatography (CH2Cl2: ethyl acetate=2:1 or pentanes: ethyl acetate=3:2 or1:1) to give the desired product as a green crystalline solid. Yield: 65.7%. Anal.
