Dissolve the indole (3.54 mmol) and N,N,-dimethylmethyleneammonium chloride (0.372 g, 4.00 mmol) in dichloromethane (15 mL), stir the mixture is at room temperature for 24˜72 h. under nitrogen. Wash with water (5 mL), follow by addition of base to neutralize the acid (3.6 mL, 1M NaOH). Extract with ethyl acetate (2×100 mL), wash with saturated NaCl, then dry over anhydrous magnesium sulfate. Remove the solvent in vacuo to give (1H-Indol-3-ylmethyl)-dimethyl-amine.
