Procedure

A solution 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 (398.4 mg, 0.745 mmol), 5-vinyl-[1,3]dioxane-5-carboxylic acid (117.9 mg, 0.745 mmol), tri(o-tolyl)phosphine (45.3 mg, 0.149 mmol) and triethylamine (0.32 mL, 2.235 mmol) in 1,4-dioxane (15 mL) was degassed by bubbling nitrogen through for 5 minutes then warmed to 50° C. and treated with tris(dibenzylideneacetone)dipalladium(0) (68.2 mg, 0.074 mmol). After stirring at 100° C. for 40 minutes the reaction was cooled to room temperature, filtered through a pad of Celite, which was rinsed with ethyl acetate. The volatiles were removed in vacuo to provide crude title compound as an orange foam that was used without further purification. LCMS (m/z) 612.2 [M+H], Tr=1.70 min.
