Reaction Steps

To a suspension of 3-(benzofuran-2-yl)quinoxalin-2-ol (Example 15b, 268 mg, 1.02 mmol) in Toluene (5.1 mL) was added thionyl chloride (0.30 mL, 4.1 mmol) followed by DMF (238 μl, 3.07 mmol). The yellow reaction mixture was stirred at 110° C. for 2 h, cooled to room temperature, and evaporated under reduced pressure to gave a yellow solid. The solid was suspended in dichloromethane (20 ml) and purified by flash chromatography on silica gel (dichloromethane) to give the title compound, 2-(benzofuran-2-yl)-3-chloroquinoxaline (297 mg, quantitative yield), as a yellow solid.
