Komponenten

Versuchsvorschrift

25 ml (87.5 mmol) of a 3.5 molar solution of sodium bis-(2-methoxyethoxy)-dihydroaluminate in toluene are added under nitrogen to a solution of 7.9 g (25 mmol) of the compound from Example 19 in 100 ml of dry tetrahydrofuran at 0° C. The mixture is stirred at room temperature for 6 h, cooled again to 0° C. and 200 ml of water are slowly added dropwise. The mixture is extracted three times using 150 ml of ethyl acetate each time, the combined organic phases are washed once with saturated sodium chloride solution, dried over magnesium sulphate and concentrated in vacuo. The residue is stirred with ether, filtered off with suction and dried in a desiccator.
