Procedure
The product of step (b) (1.3 g, 3.79 mmole) and phosporyl chloride (0.69 ml) in dry dichloroethane (80 ml) were heated to reflux for 15 minutes. The reaction mixture was then cooled and treated with water. The mixture was extracted with dichloroethane, the organic layer was washed with water, dried, and evaporated to give a brown solid. This was dried in vacuo over P2O5 at 50° C. to give the sub-title compound (0.9 g; 66%).
