Participants

Reaction Steps

Acetic anhydride (1.4 mL, 15 mmol) was added to a suspension of Example 141C (5 mmol) and triethylamine (0.76 mL, 5.5 mmol) in CH2Cl2 (20 mL) at ambient temperature. The mixture was stirred for 3.5 hours, then the volatiles were removed under reduced pressure. The residue was chased with toluene (3×25 mL) and concentrated under reduced pressure to afford the title compound (0.40 g, 33% yield over three steps). MS (ESI) m/z 246 (M+H)+.
