Sodium thiomethoxide (280 mg, 4.00 mmol) and KI (10 mg, 0.06 mmol) were added to a soluton of 5-chloro-N-[1-(2-chloroethyl)-2-oxo-1,2,3,4-tetrahydroquinolin-3-yl]-1H-indole-2-carboxamide (Method 3; 1.07 g, 2.67 mmol) in DMF (10 mL) under an inert atmosphere and heated at 80° C. for 2 hours. On cooling the mixture was diluted with EtOAc (100 mL), washed with water (20 mL), dried (Na2SO4), filtered and evaporated. The residue was purified by column chromatography (DCM to DCM:THF (2:23)) to give a white solid. The solid was triturated with refluxing Et2O (20 mL) and the solid filtered, washed with Et2O (10 mL) then hexane (10 mL) to afford the title compound (410 mg, 37%) as an off white solid.
