Procedure

1-{2-(hex-5-enylmethylcarbamoyl)-4-[2-(6-isopropyl-2-pyridyl)-7-methoxy-8-methyl-quinolin-4-yloxy]cyclopentanecarbonyl}amino-2-vinyl-cyclopropanecarboxylic acid ethyl ester (111, 438 mg, 0.50 mmol) was dissolved in dry 1,2-dichloroethane. Then, nitrogen gas was bubbled through the solution for 30 min before Hoveyda-Grubbs 1st generation (15 mg) was added. The resulting solution was refluxed for 3 h, then more catalyst (20 mg) was added. After 2 h at reflux, another 10 mg of the catalyst was added. After 12 h at reflux, the reaction mixture was cooled down to room temperature. Then, scavenger MP-TMT (Agronaut Technologies Inc.) was added (˜300 mg) and the mixture was stirred at room temperature for 45 min. The catalyst was discarded by filtration on silica gel (gradient of CHCl3/MeOH, 1:0 to 98:2) to give 220 mg (66%) of the title compound 112: m/z=669 (M+H)+.
