Procedure
Hoveyda-Grubbs 2nd generation catalyst (22 mg, 0.035 mmol) was added to a stirred solution of (S)-1-{(S)-3-[3-(tert-butyl-dimethyl-silanyloxy)-phenyl]-2-[(S)-2-((2R,3R)-3-methoxy-2-methyl-hept-6-enoylamino)-3-methyl-butyrylamino]-prop ionyl}-hexahydro-pyridazine-3-carboxylic acid 4-vinyl-pyridin-2-ylmethyl ester (276 mg, 0.35 mmol) in 1,2-dichloroethane (130 mL) and the reaction mixture was heated at 80° C. under nitrogen for 3 hours. The reaction mixture was cooled to room temperature, silica gel was added and the solvent was evaporated. The residue was purified by silica gel chromatography using a gradient of iso-hexanes/ethyl acetate 1:1 to neat ethyl acetate to afford (E)-(1S,14R,15R,18S,21S)-21-[3-(tert-butyl-dimethyl-silanyloxy)-benzyl]-18-isopropyl-14-methoxy-15-methyl-3-oxa-6,17,20,23,27-pentaaza-tricyclo[21.3.1.1*5,9*]octacosa-5(28),6,8,10-tetraene-2,16,19,22-tetraone (160 mg, 61%) as a white solid. LCMS (m/z) 750 [M+H], Tr=5.58 min.
