Sažetak

From indole and 5-benzyloxyindole, respectively, the corresponding
chloromethyl 3-indolyl ketones were prepared applying
Guignard reaction with chloroacetyl chloride or Vilsmeier reaction
with N,N-diethylchloroacetamide. By i. r. and n. m. r. spectroscopy
it was proved that identical compounds were obtained in both
reactions.
After the substitution of the halide with dibenzylamino group
and the reduction of the carbonyl group to hydroxyl with lithium
alumi.num hydride, benzyl groups were removed by catalytic
hydrogenation.
3-(2-Amino-1-hydroxyethy l)indole (beta-hydroxytryptamine)
and 5-hydroxy-3-(2-amino-1-hydroxyethyl)indole (beta-hydroxyserotonin)
were isolated in the form of crystalline creatinine
sulphates. Solubility and satisfying stability in aqueous solutions
make these salts suitable for biochemical and pharmaco'logical
investigations.
