Procedure
Thionylchloride (0.42 ml, 6.0 mM) was added dropwise under ice-cooling to compound 109 (1.22 g, 50 mM) dissolved in chloroform (10 ml), and stirred at room temperature for 3 hours. Chloroform was added to the reaction mixture, whereafter the mixture was washed with dilute aqueous K2CO3 and the resultant aqueous layer extracted with further chloroform. The chloroform layer was combined, dried with anhydrous magnesium sulfate and concentrated in vacuo. The residue was charged on a column of silica-gel (C-200, 25 g), and eluted with chloroform to obtain compound 612 (0.59 g, yield: 42.7%).
