Versuchsvorschrift

A solution of 0.6 g (1.4 mmol) of 2-(3,4-dichlorophenyl)-2-hydroxy-N-[trans-2-(4-hydroxy-3-methoxy-phenyl)-cyclohexyl]-acetamide and 0.4 g (1.9 mmol) of propynyl tosylate and 2.7 ml of 1 M solution of sodium methoxide in 10 ml methanol is heated to reflux for 3 hours. The reaction mixture is cooled and poured into 30 ml of aqueous saturated sodium chloride solution and finally extracted with two 100 ml portions of ethyl acetate. The combined organic extract is concentrated under reduced pressure to a residue, which is subjected to column chromatography on silica gel, with 1:1 ethyl acetate/isohexane as the eluant to obtain 2-(3,4-dichlorophenyl)-2-hydroxy-N-[trans-2-(3-methoxy-4-prop-2-ynyloxy-phenyl)-cyclohexyl]-acetamide.
