Reaction Steps

To a solution of quinoline-N-oxide (0.5 mmol) in 2 mL DCM at 0° C. in a 3 mL plastic tube fitted with a frit was added 58 uL of benzoyl chloride (0.5 mmol). The reaction mixture was stirred for 15 min at 0° C. and then indole (0.5 mmol) was added. The reaction was warmed to 20° C. and stirred for 4 h. The solid precipitate was filtered and washed with DCM (3×2 mL) to give solid 2-(3-indolyl)quinoline (6-100% yield).
