Reaction Steps

The title A indole (819 mg, 4.67 mmol, 1.0 eq.) and 4-bromotoluene (1.44 ml, 11.69 mmol, 2.5 eq.) were dissolved in pyridine (4.7 ml, 1M) in an argon atmosphere. Copper(I) oxide (668 mg, 4.67 mmol, 1.0 eq.) was added and heated at 130°±5° C. for 8.5 hours. Ethyl acetate was added and the solid was removed by filtration through celite. The filtrate was washed with water (3×40 ml), 0.5N hydrochloric acid (2×50 ml) and saturated sodium hydrogen carbonate solution (40 ml), dried over anhydrous magnesium sulfate and freed of solvent in vacuo. The remaining brown oil was chromatographed on silica gel, eluting with 10% ether in hexane to give the title B compound (1.165 g).
