Procedure
To a mixture of EXAMPLE 199B (2 g) in dichloromethane (10 ml) was added trifluoroacetic acid (10 ml) at 0° C. The reaction mixture was stirred at room temperature for 30 minutes and concentrated. The residue was loaded onto a C18 column, and eluted with 0-50% 0.1% trifluoroacetic acid/water in acetonitrile. The title compound was obtained as a trifluoroacetic acid salt.
