Procedure
A suspension of EXAMPLE 428B (2.018 g) in anhydrous dichloromethane (25 mL) was cooled in an ice bath and 2,2,2-trifluoroacetic acid (20 mL) was added. After stirring 15 minutes, the ice bath was removed and the reaction was allowed to come to ambient temperature over 2 hours. The reaction mixture was concentrated and the residue was dissolved in water and basified with aqueous sodium carbonate solution. The mixture was extracted repeatedly with 10% methanol in methylene chloride and the organics were concentrated to provide the title compound.
