Versuchsvorschrift

A 100 mL Schlenk flask was charged with (6-chloropyridin-3-yl)(4-(tetrahydro-2H-pyran-2-yloxy)phenyl)methanone (4.0 g, 12.6 mmol), tetrakis(triphenylphosphine) palladium(0) (1.5 g, 1.3 mmol, 10 mol %), cuprous iodide (0.48 g, 2.5 mmol, 20 mol %), triethylamine 50 mL and 1-(prop-2-ynyl)pyrrolidine (2.8 g, 25.2 mmol), and then the flask was flushed with nitrogen three times. The mixture was stirred at 80° C. for 2 h. The solvent was evaporated under vacuum and the residue was purified by column chromatography to afford the desired product as a yellow solid (2.2 g, 44.9% yield).
