Participants

Reaction Steps

To a solution of Example 235a (1.04 g, 5.9 mmol) in 12 mL anhydrous DMF was added N-iodosuccinimide (1.46 g, 6.49 mmol) and the solution stirred at room temperature for 16 hours. The solvent was evaporated and the residue suspended in water and filtered. The collected solid was triturated with dichloromethane and the mixture filtered. The dichloromethane filtrate was concentrated to a brown powder that was carried on without purification.
