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 (68 mg, 0.128 mmol), 6-vinyl-[1,4]dioxepane-6-carboxylic acid (22 mg, 0.128 mmol), triethylamine (39 mg, 54 μL, 0.384 mmol) and tri(o-tolyl)phosphine (8 mg, 0.026 mmol) in 1,4-dioxane (2 mL) was deoxygenated by bubbling nitrogen through for 5 minutes and then warmed to 50° C. under nitrogen with stirring. Tris(dibenzylideneacetone)dipalladium(0) (12 mg, 0.013 mmol) was added and the mixture was refluxed for 40 minutes and then allowed to cool. The suspension was filtered and the filtrate was evaporated to give crude title compound which was used directly in the next stage. LCMS (m/z) 626.2 [M+H], Tr=1.67 min.
