Abstract

The invention comprises 6-fluorotryptamine and its acid addition salts, such as the picrate, hydrochloride, and sulphate, and the production of 6-fluorotryptamine by diazotising 2-nitro-4-aminotoluene, treating with fluoboric acid, and heating to prepare 2-nitro-4-fluorotoluene, condensing with ethyl oxalate in the presence of an alkali metal ethylate and isolating the alkali metal salt of ethyl 41-fluoro-21-nitro-phenyl pyruvate, treating with acid to obtain the ester, reducing, and cyclising to form ethyl 6-fluoro-indole-6-carboxylate by the action of a reducing agent in an acid medium; the indole derivative is saponified and decarboxylated to 6-fluoroindole, which is condensed with dimethylamine and formaldehyde to form 6-fluorogramine, which is isolated, quaternised with methyl sulphate and reacted with an alkali metal cyanide; the 6-fluoro-3-indolyl-acetonitrile is isolated and catalytically hydrogenated to yield 6-fluorotryptamine. 6-fluorotryptamine is an intermediate in the synthesis of compounds of the reserpine series, and is an antimetabolite for tryptophane; it may be used when the microbiological conversion of tryptophane to indole is to be avoided, e.g. in pathological intestinal fermentations.
