By reaction of 3-(2-methyl-2-aminopropyl)indole (I) and 2-(2,3-epoxypropoxy)benzonitrile (II) by heating at 120-40 C followed by a treatment with HCl in ethanol. The starting products are obtained as follows: 1) The reaction of 3-(dimethylaminomethyl)indole (III) with 2-nitropropane (IV) by means of KOH gives 3-(2-methyl-2-nitropropyl)indole (V), which is then reduced with hydrazine and Raney-Ni in ethanol to yield (I). 2) The reaction of 2-hydroxybenzonitrile (VI) with epichlorohydrin (VII) by means of piperidine affords 2-(3-chloro-2-hydroxypropoxy)benzonitrile (VIII), which is epoxidized again to (II) by treatment with NaOH in hot THF-water.
