Procedure
To a solution of EXAMPLE 291C (4.14 g) in dichloromethane (10 mL) was added trifluoroacetic acid (10 mL). The mixture was stirred for 2 hours. The mixture was concentrated under vacuum and the residue was dissolved in dichloromethane (300 mL) and washed with aqueous NaHCO3, water, and brine and dried over Na2SO4. Filtration and evaporation of solvent gave the title compound.
