To a solution of 7-amino-3-(morpholin-4-ylsulfonyl)-1H-indole-2-carboxamide from Example 7 (52 mg, 0.16 mmol) in 1 mL of dichloromethane at 0° C. was added triethylamine (0.067 mL, 0.91 mmol) and acetic anhydride (0.058 mL, 0.52 mmol). After two hours, the mixture was partitioned between ethyl acetate and 3N HCl solution, and the organic layer was washed with saturated NaHCO3 solution and brine, dried (Na2SO4), filtered, and concentrated in vacuo to provide the titled compound. HRMS (ES) exact mass calculated for C15H18N4O5SNa (M+Na+): 389.0890. Found 389.0889.
