Versuchsvorschrift

(3-Bromo-phenyl)-(7,8,10,11,13,14-hexahydro-6,9,12,15-tetraoxa-1,3-diaza-cyclododeca[b]naphthalen-4-yl)-amine (Compound 10) (10 mg, 0.5 mmol) was dissolved in DMF (10 mL). Tetrakis(triphenylphosphine) palladium (20 mg), trimethylsilylacetylene (70 microliter, 0.65 mmol), potassium carbonate (10 mg) and copper (I) iodide (5 mg) was added under nitrogen atmosphere. The reaction mixture was refluxed for about 3 h and then the reaction cooled and concentrated in vacuo, to afford a residue, which was flash chromotographed to provide a white solid (20 mg). ES-MS m/z 392 (MH+).
