Participants

Reaction Steps

To a solution of Example 17D (32 mg, 0.1 mmol) in anhydrous THF (5 mL) was added N,N-diisopropylethylamine (0.035 mL, 0.2 mmol), followed by phenyl chloroformate (17.22 mg, 0.11 mmol). The mixture was stirred for 8 hours at room temperature and concentrated under reduced pressure. The residue was taken up in anhydrous dichloromethane (3 mL) and trifluoracetic acid (0.075 mL) in dichloromethane (0.075 mL) were added. The mixture was stirred for 5 hours at room temperature, concentrated under reduced pressure and purified using RP-HPLC to provide the titled compound.
