Reaction Conditions

Reaction Steps

To a solution of 0.6 g (1.4 mmol) of the compound prepared in (e) above in 30 ml of dry pyridine was added 0.37 g (0.82 mmol) of phosphorus pentasulfide, and the resultant mixture was heated to 90° C. and maintained at this temperature for 30 minutes under a nitrogen atmosphere. After cooling the reaction mixture to 25° C., the solvent was evaporated and the resultant residue was diluted with methylene chloride. The organic phase was then washed successively with water and brine, dried over anhydrous magnesium sulfate and evaporated to yield a red foam.
