Reduction of the Schiff base (XVIII), obtained by the condensation of 2-amino-4, 5-dimethoxyphenethyl alcohol (XII) with 6-nitroveratraldehyde, afforded 2-(4, 5-dimethoxy-2-nitrobenzylamino)-4, 5-dimethoxyphenethyl alcohol (XIX). Cyclization of XIX with thionyl chloride, followed by the reduction of 2, 3-dihydro-5, 6-dimethoxy-1-(4, 5-dimethoxy-2-nitrobenzyl) indole (V) with zinc powder, gave the corresponding 1-(2-amino-4, 5-dimethoxybenzyl)-2, 3-dihydro-5, 6-dimethoxyindole (VI).
