Participants

Reaction Steps

A solution of Example 145A (180 mg, 0.521 mmol) and disuccinimidyl carbonate (0.16 g, 0.625 mmol) in dichloroethane (5 mL) was treated with triethylamine (87 μL, 0.625 mmol) at 25° C. for 16 h. The mixture was partitioned between 10% sodium carbonate and dichloromethane. The organic layer was separated, washed with brine, dried over MgSO4, filtered, and the solvents were evaporated to give the crude residue which was purified using silica gel chromatography eluting with a gradient of 100% hexanes to 60% hexanes in ethyl acetate to give the title compound (0.127 g, 67%).
