Reaction Conditions

Reaction Steps

To a solution of Example 288c (0.671 g, 3.87 mmol) and sodium acetate (0.318 g, 3.87 mmol) in acetic acid (8.50 mL) was added bromine (0.201 mL, 3.91 mmol) dropwise as a solution in acetic acid (1.7 mL). The reaction mixture was stirred at 40° C. for 3 hours. Bromine (0.05 mL) was added, and the reaction mixture was stirred at 40° C. for 2 hours. The reaction mixture was cooled to ambient temperature and quenched with 100 mL of 10% aqueous sodium thiosulfate. The resulting suspension was filtered, and the solid collected and dried for 16 hours to provide the title compound (0.64 g, 66%).
