Procedure

A mixture of (S)-1-[(S)-2-((S)-2-hydroxy-3-methyl-butyrylamino)-propionyl]-hexahydro-pyridazine-3-carboxylic acid [(R)-1-(7-bromo-quinolin-2-yl)-ethyl]-amide (198 mg, 0.371 mmol), 5,5-dimethyl-2-vinyl-[1,4]dioxane-2-carboxylic acid (69 mg, 0.371 mmol), triethylamine (112 mg, 155 μL, 1.11 mmol) and tri(o-tolyl)phosphine (23 mg, 0.074 mmol) in 1,4-dioxane (7.5 mL) was degassed with nitrogen for 5 min and then warmed to 50° C. under nitrogen with stirring. Tris(dibenzylideneacetone)dipalladium(0) (34 mg, 0.037 mmol) was added and the mixture was heated to 80° C. for 40 min and then allowed to cool to room temperature. The suspension was filtered and evaporated to give crude title compound (0.371 mmol) which was used directly in the next stage. LCMS (m/z) 640.3 [M+H], Tr=1.94 min.
