Reaction Steps

A suspension of p-aminophenol linked to the Wang's resin from Step A (1 eq) in dichloromethane was treated with triethylamine (2 ml/mmol) and 2-chloro-benzoyl chloride (10 eq). The mixture reaction was stirred for 1 hour and then the resin was filtered, washed with MeOH/CH2Cl2 several times and dried. The resin was then treated with TEA 95% H2O 5% and stirred at room temperature for 30 minutes. Filtered and washed with dichloromethane/methanol and concentrated to dryness to afford the title compound.
