Versuchsvorschrift

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 (95 mg, 0.178 mmol), 2-vinyl-morpholine-2,4-dicarboxylic acid 4-tert-butyl ester (45.7 mg, 0.178 mmol), tri(o-tolyl)phosphine (11 mg, 0.036 mmol) and triethylamine (0.08 mL, 0.534 mmol) in 1,4-dioxane (5 mL) was degassed by bubbling nitrogen through for 5 minutes then warmed to 50° C. and treated with tris(dibenzylideneacetone)dipalladium(0) (16.3 mg, 0.018 mmol). After stirring at 100° C. for 50 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) 711.3 [M+H], Tr=2.14 min.
