To a solution of 7-amino-3-(morpholin-4-ylsulfonyl)-1H-indole-2-carboxamide from Example 7 (109 mg, 0.336 mmol) in 5 mL of acetic acid was added a 3.3 M stock solution of bromine in acetic acid (0.12 mL, 0.40 mmol). After 30 minutes, the mixture was partitioned between ethyl acetate and saturated NaHCO3 solution. The organic layer was washed with brine, dried (Na2SO4), filtered, and concentrated in vacuo. Purification by preparative reversed phase HPLC provided the titled compound. Proton NMR for the product was consistent with the titled compound. HRMS (ES) exact mass calculated for C13H16BrN4O4S (M+H+): 403.0070. Found 403.0069.
