Versuchsvorschrift

A solution of 2.9 g of 4-(2-nitrophenyl)but-3-yn-1-ol in 750 ml of acetonitrile is admixed at room temperature with 17.5 g of silver oxide and 9.4 ml of methyl iodide and stirred at 50° C. over 70 hours. The reaction mixture is clarified by filtration and the filtrate is concentrated by evaporation. The title compound is obtained as a yellow oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.34 (1:2 EtOAc-heptane); Rt=4.17.
