Reaction Steps

Following the procedure as described in Example 3, except using material from Example 75 (100.2 mg, 0.129 mmol), CH2Cl2 (2 mL), TFA (2 mL, 26 mmol) and stirring at room temp for 2 h, the title compound (quantitative yield) is isolated as an off white solid, as a TFA salt, that is used directly “as is” in the next coupling step. LC/MS (Condition A): ret. T=1.88 min, (M+H)+ 562.37.
