Reaktionsschritte

N-(2-Chloro-quinolin-5-yl)-3,5-difluoro-benzenesulfonamide (150 mg, 0.423 mmol) was dissolved in 3 mL dioxane. Argon was bubbled through the solution for 2 minutes to remove oxygen. (2-Methyl-1-benzofuran-7-yl)amine (245 mg, 1.33 mmol), sodium tert.-butylate (230 mg, 2.40 mmol), 1,1′-bis(diphenylphosphin)ferrocen (36 mg, 0.06 mmol) and 1,1′-bis(diphenylphosphin)ferrocen-palladium(II)chloride (17 mg, 0.02 mmol) were added. The reaction mixture was stirred in a sealed tube at 100° C. for 16 h. The solvent was evaporated and the residue purified by flash chromatography on silica gel (heptane/ethyl acetate 100:0->60:40 gradient). The title compound was obtained as a light brown solid (164 mg, 83%), MS: m/e=466.0 (M+H+).
