Reaction Conditions

Reaction Steps

To a solution of Example 75 (6 mg, 0.013 mmol) in THF (200 μl) at 0° C. was added Et3N (3 μl, 0.021 mmol) followed by the acetic anhydride (5 μl, 0.04 mmol). The reaction mixture was stirred at 0° C. for 5 minutes and then at rt for 10 minutes. The solvent was evaporated under pressure, and the residue was purified by preparative HPLC using 0 to 100% B over 10 minutes (Column, Luna 10μ, C18 25×100 mm; Solvent A, 10% ACN +90% H2O with 0.1% TFA; Solvent B, 90% ACN+10% H2O with 0.1% TFA) to afford the title compound (2.8 mg, 48%) as a white lyophilite. MS m/z 486 ([M+H]+).
