Versuchsvorschrift

Diisobutylaluminum hydride (1 M in toluene, 15 mL) was slowly added to a suspension of 2-(6-methoxy-1H-indol-3-yl)ethylamine (250 mg) in 20 mL of toluene. The resulting clear solution was refluxed for 10 h, then cooled to 0° C. and quenched by the careful addition of 20 mL of 1:1 methyl alcohol:water. The mixture was stirred for 15 min at rt and filtered to remove the precipitated aluminum salts. The solvent was evaporated to yield 158 mg of 3-(2-amino-ethyl)-1H-indol-6-ol.
