Reaction Steps

A solution of the product from Example 117C (0.098 mmol) in dichloromethane (0.5 mL) was treated with trifluoroacetic acid (0.5 mL) and the mixture was stirred for 1 hour at 25° C. The solvent was removed under reduced pressure and the residue was purified by reversed phase chromatography on a C18 column eluting with 5-100% acetonitrile in water (0.1% TFA) to give the title compound as the trifluroacetic acid salt (0.022 g, 52% yield).
