Procedure

The product from Example 1B (31.3 g, 100 mmol) in THF (300 mL) and 10% Na2CO3 (250 mL) at 0° C. was treated dropwise with benzyl chloroformate (18.0 g, 105 mmol), stirred vigorously for 30 minutes, and extracted with diethyl ether. The organic layer was washed with brine, dried (MgSO4), and concentrated to provide the title compound.
