Reaction Steps

N-(2-Chloro-quinolin-5-yl)-3,4,5-trifluoro-benzenesulfonamide (150 mg, 0.402 mmol) was dissolved in 5 mL dioxane. Argon was bubbled through the solution for 2 minutes to remove oxygen. rac-2,3-Dihydro-benzofuran-3-ylamine (CAS 109926-35-4, 82 mg, 0.607 mmol), sodium tert.-butylate (97 mg, 1.01 mmol), 1,1′-bis(diphenylphosphin)ferrocen (33 mg, 0.06 mmol) and 1,1′-bis(diphenylphosphin)ferrocen-palladium(II) chloride (16 mg, 0.02 mmol) were added. The reaction mixture was stirred in a sealed tube at 120° C. for 6 hours. The solvent was evaporated and the residue purified by flash chromatography on silica gel (heptane/ethyl acetate 100:0->70:30 gradient). The title compound was obtained as a yellow foam (100 mg, 53%), MS: m/e 472.4 (M+H+).
