Reaction Steps

100 ml of a 1N solution of potassium tert-butoxide in tetrahydrofuran is added dropwise to a solution, cooled to −20° C., of 0,1 mol of methyl 5-methoxy-1H-indolecarboxylate in tetrahydrofuran. The medium is stirred for 30 minutes at this temperature, followed by dropwise addition of a solution of 0.1 mol of methyl iodide in tetrahydrofuran. Once the addition is complete, the medium is warmed slowly to room temperature, stirred for 1 h at this temperature and filtered. The expected product is obtained after concentration of the solvent.
