Versuchsvorschrift
To a solution of 5-methoxy-2-(3-methylbut-1-ynyl)aniline (Compound 135, 1.8 g, 9.5 mmol) in DMF (20 ml) was added CuI (101 mg, 0.53 mmol). The reaction was stirred at 160° C. for 1.5 h. The solvent was removed in vacuo and the residue was purified by chromatography on silica gel (0→25% EtOAc-hexanes) to yield the title compound as a brownish red solid.
