Versuchsvorschrift
A solution of thionyl chloride (139.0 g, 1.17 mol) in dry DMF (150 ml) was added to a stirred solution of compound 26 (20.0 g, 0.11 mol) in dry DMF (250 ml) at room temperature. The mixture was stirred at room temperature overnight and then poured onto ice-water. The product was extracted into ether (twice), and the combined ethereal extracts were washed with water, saturated sodium hydrogen carbonate, water and dried (MgSO4). The solvent was removed in vacuo to give off-white crystals.
