Procedure
27.3 g (0.116 mol) of the compound from Example VI are boiled under reflux with 18.3 g of PCl5 and 200 ml of POCl3 for 18 h. The mixture is added to ice with good stirring and extracted with methylene chloride, and the organic phase is washed with saturated NaHCO3 solution, dried and evaporated in vacuo. 12 g (41% crude yield) of a solid are obtained, which after chromatography has a m.p. of 128° C.
