Procedure

A solution of EXAMPLE 369A (0.8 g) in methylene chloride (10 mL) and trifluoroacetic acid (10 mL) was stirred at room temperature for 2 hours. The solvents were evaporated and the residue was triturated with diethyl ether. The resulting solid was dissolved in 5% aqueous sodium carbonate solution (20 mL). The mixture was concentrated to dryness and the resulting solid was triturated with a solution of 10% methanol in methylene chloride several times. Evaporation of the organic solvent provided the title compound.
