Versuchsvorschrift

A 10 mL reaction vessel was charged with compound 245 (75.0 mg, 276 μmol), (R)-5-(3-(t-butyldimethylsilyloxy)pyrrolidin-1-yl)-2-chloropyridine (86.5 mg, 276 μmol), tris(dibenzylideneacetone)dipalladium (0) (19.0 mg, 20.7 μmol), 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (24.0 mg, 41.5 μmol), sodium t-butoxide (53.1 mg, 553 μmol), and dioxane (1.5 mL). The reaction was heated with microwave energy (300 W) for 2 hours at 120° C. in the resulting solution was added to ethyl acetate (40 mL) and washed with water (30 mL) followed by brine (30 mL). The organic phase was dried (MgSO4) and evaporated to give an orange oil. Silica gel chrmatography (gradient elution 35% ethyl acetate in hexanes) afforded compound 278 as a yellow solid (59 mg, 39%)
