Procedure

5-Bromo-3-(morpholin-4-ylsulfonyl)-1H-indole-2-carboxamide (106 mg, 0.273 mmol, 1.0 equiv), dichlorobis(triphenylphosphine)palladium(II) (50 mg, 0.07 mmol, 0.15 equiv) and tetramethyltin (270 μL, 1.91 mmol, 4.0 equiv) were combined in 5 mL of a 1:1 solution of DMF:HMPA. The solution was degassed and heated to 120° C. for 24 hours. The title compound was obtained after purification by preparative reversed phase HPLC. Proton NMR for the product was consistent with the titled compound. HRMS (ES) exact mass calculated for C14H18N3O4S (M+H+): 324.1013. Found 324.1014.
