Procedure

Thionylchloride (2.05 ml) was added dropwise under ice-cooling to compound 645 (6.49 g, 22.1 mM) dissolved in chloroform (25 ml), and stirred at room temperature for 2 hours. Dilute aqueous K2CO3 was added to the reaction mixture, which mixture was then extracted twice with chloroform. The extract was dried with anhydrous sodium sulfate and concentrated in vacuo to obtain compound 647, which was used without further purification in the following reactions.
