Procedure
To the product from Example 11 in 2 mL of acetone was added 1.33M Jones reagent until an orange color persisted. The reaction was poured into 20 mL of ethyl acetate and 20 mL of H2O and the organic layer separated, washed with saturated sodium bisulfite and dried over MgSO4. The crude product was filtered through silica gel/Celite to afford the title compound as a yellow solid: HRMS m/z 411.0507 (calc'd for C17H12N3O4SF3, 411.0500).
