Versuchsvorschrift

A solution of (S)-1-[(S)-2-(2-cyclopropyl-2-hydroxy-acetylamino)-propionyl]-hexahydro-pyridazine-3-carboxylic acid [(R)-1-(7-bromo-quinolin-2-yl)-ethyl]-amide (592 mg, 1.11 mmol), 5-vinyl[1,3]dioxane-5-carboxylic acid (176 mg, 1.11 mmol), triethylamine (343 mg, 472 μL, 3.39 mmol) and tri(o-tolyl)phosphine (67 mg, 0.22 mmol) in 1,4-dioxane (15 mL) was degassed with nitrogen for 5 minutes and then warmed to 50° C. under nitrogen with stirring. Tris(dibenzylideneacetone)dipalladium(0) (101 mg, 0.11 mmol) was added and the mixture was heated to reflux for 20 minutes and then allowed to cool to room temperature. The suspension was filtered through Celite and the filtrate evaporated to give crude 5-((E)-2-{2-[(R)-1-({(S)-1-[(S)-2-(2-cyclopropyl-2-hydroxy-acetylamino)-propionyl]-hexahydro-pyridazine-3-carbonyl}-amino)-ethyl]-quinolin-7-yl}-vinyl)-[1,3]dioxane-5-carboxylic acid.
