Procedure

1-{2-(Hex-5-enylmethylcarbamoyl)-4-[2-(6-methyl-2-pyridyl)-7-methoxy-8-methyl-quinolin-4-yloxy]cyclopentanecarbonyl}amino-2-vinylcyclopropanecarboxylic acid ethyl ester (100, 250 mg, 0.37 mmol) was dissolved in dry 1,2-dichloroethane (250 mL). Then, nitrogen gas was bubbled through the solution for 30 min before Hoveyda-Grubbs 2nd generation (25 mg) was added. The resulting solution was refluxed overnight, then cooled down to room temperature and evaporated. The residue was purified by column chromatography on silica gel (gradient AcOEt/Heptane, 3:7 to 5:5) to give 139 mg (58%) of the title compound 101.
