Versuchsvorschrift

3-(4-(methylsulfonamido)phenyl)-4-oxo-4H-chromen-7-yl trifluoromethanesulfonate (2.5 g, 5.39 mmol), trimethylsilylacetylene (0.92 ml, 1.2 eq), PdCl2(PPh3)2 (175 mg, 0.05 eq), copper iodide (28.8 mg 0.03 eq), triphenylphosphine (40 mg 0.03 eq) and triethylamine (3.12 ml, 4.0 eq) were combined in dry tetrahydrofuran (10 ml) and heated in microwave for 30 minutes at 85° C. The reaction mixture was partitioned between ethyl acetate and water, the organic phase dried with magnesium sulfate, and solvent removed under reduced pressure. The crude product was heated in acetonitrile, cooled down and the solids were filtered off. This procedure was repeated twice in order to afford N-(4-(4-oxo-7-((trimethylsilyl)ethynyl)-4H-chromen-3-yl)phenyl)methanesulfonamide.
