実験手順

To a stirred solution of Example 13 Part A compound (222 mg, 0.45 mmol) under argon at room temperature in CH2Cl2 (2.5 mL) was added triethylamine (85 μL, 0.6 mmol), HOAt (69 mg, 0.5 mmol) and difluoroacetic acid (48 mg, 0.5 mmol) was added EDAC (96 mg, 0.5 mmol). After 16 h, the reaction mixture was diluted with EtOAc, washed once with 10% citric acid, dried (MgSO4) and evaporated. Purification by flash chromatography on silica gel provided the title compound as a colorless oil, 156 mg (64% yield). LC/MS gave the correct molecular ion [(M+H)+=538] for the desired compound.
