Procedure
A mixture of N-[2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-yl]ethane-1,2-diamine (150 mg, 0.38 mol, prepared in analogy to Example 9-16), 2-bromo-pyridine (60 mg, 0.38 mol), tri(dibenzylideneacetone)dipalladium(0) (17.4 mg, 0.019 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthe (22 mg, 0.038 mmol), cesium carbonate (247.6 mg, 0.76 mmol) and N-methylpyrrolidinone (3 mL) was heated with stirring at 150° C. for 6 hours under nitrogen. The mixture was diluted with ethyl acetate, washed with water, dried over sodium sulfate, filtered, concentrated in vacuo. The residue was purified by preparative HPLC to give 10 mg of produce as an off-white solid. MS obsd.
