Participants

Reaction Steps

To 152 mg (0.76 mmol) 4-benzyloxy-1H-pyridin-2-one in THF at 0° C. is added subsequently 492 mg (1.51 mmol) cesium carbonate, 14 mg (0.08 mmol) tetra-butylammonium-iodide and 300 mg (0.76 mmol) 2,2,2-trifluoro-1-[7-(2-iodo-ethyl)-1,2,4,5-tetrahydro-3-benzazepin-3-yl]-ethanone (preparation 6b). The reaction mixture is stirred overnight at RT, diluted with DMF and filtered. The residue is purified via reverse HPLC chromatography (Zorbax stable bond, C18; water (0.1% formic acid)/acetonitrile (0.1% formic acid) 95:5 to 5:95).
