Reaction Steps

The title compound was prepared following procedure described for example 4, step 1, but starting from Intermediate 49 (142.14 mg; 0.50 mmol) and Intermediate 3 (135.76 mg; 0.60 mmol). The reaction mixture was filtered through a SPE NH2 column (2 g) and rinsed with ACN. The filtrate was passed through a SPE SCX column (2 g) and rinsed with ACN. After evaporation of the solvents, the crude product was purified by flash chromatography (c-hex/EtOAc: 9.5/0.5), affording the title compound as a colorless oil. LC/MS (Method B): 475.4 (M+H)+. HPLC (Method A) Rt 6.78 min (Purity: 99.3%).
