Procedimiento

Methyl 1H-indole-6-carboxylate (4.17 g) was dissolved in DMSO (30 mL), and potassium tert-butoxide (2.93 g) was added. The mixture was stirred for ten min at room temperature. Iodobutane (3.0 mL) was added. The mixture was allowed to stir for three additional hours. The mixture was partitioned between ethyl acetate and water and brine, dried over sodium sulfate, filtered, and concentrated to give methyl 1-butyl-1H-indole-6-carboxylate (4.53 g).
