Versuchsvorschrift

The (4-benzyloxy-phenyl)-(6-iodoquinazolin-4-yl)-amine hydrochloride (1.0 g, 2.04 mmol) was reacted with trimethylsilylacetylene (8.0 ml, 5.56 g, 5.66 mmol), triethylamine (5.0 ml, 3.63 g, 3.58 mmol), bis(triphenylphosphine)palladium (II) chloride (0.10 g, 0.14 mmol) and copper(I)iodide (0.10 g, 0.53 mmol) at room temperature in acetonitrile (15 ml) under a nitrogen atmosphere overnight. Purification by silica gel chromatography (eluting with 50% i-hexane/EtOAc) gave the title compound as an off-white solid (0.70 g, 1.65 mmol, 81%).
