Reaction Steps

Add 7-formylindole (1.0 g, 6.89 mmol) in anhydrous tetrahydrofuran (15 ml) dropwise to a solution of 1.4M methyllithium in diethyl ether (12.2 ml, 17.1 mmol) at −78° C. After 15 minutes add saturated aqueous sodium bicarbonate (15 ml). Dilute with 1:1 ethyl acetate:diethyl ether, wash with saturated aqueous sodium bicarbonate followed by saturated aqueous sodium chloride, dry over magnesium sulfate, and concentrate under reduced pressure to provide desired compound (1.05 g, 94%) as a white solid.
