Procedure

The product from Example 76D (2.3 g, 4.6 mmol) and triethylamine (4.48 mL, 32.1 mmol) in DMSO (25 mL) was treated with sulfur trioxide pyridine complex (2.92 g, 18.4 mmol). After 5 hours, the mixture was partitioned between ethyl acetate and 1N HCl. The separated organic phase was washed with 1N HCl, brine, and concentrated under reduced pressure. The residue was dissolved in THF (30 mL) and saturated aqueous Na2CO3 solution (30 mL) was added. After stirring vigorously for 1 hour, the separated aqueous layer was acidified and extracted with ethyl acetate. The organic extracts were combined, washed with brine, dried (Na2SO4), filtered and the filtrate concentrated under reduced pressure to provide the title compound as a pale yellow solid (1.73 g).
