Patent GB-664471-A (GB)
Title: Process for the manufacture of new compounds of the type of ergot alkaloids
IPC: H04N7/087
Filed: 1949-09-14
Abstract: Amides similar to ergot alkaloids are made by reacting the azide of lysergic, isolysergic, dihydrolysergic or dihydroisolysergic acid with an amino acid whose carboxylic group may be free or in the form of an ester or amide.  The hydrazoic acid liberated is preferably neutralized by adding potassium carbonate or using an excess of the amino compound.  The amino acid derivative used may be a di- or polypeptide.  The products derived from lysergic and isolysergic acids are interconvertible in the same way as the natural ergot alkaloids, and a mixture is often obtained by the process of the invention.  The products may be isolated by chromotography and converted into salts, e.g. hydrochlorides, oxalates.  In the examples, the following amino acids and derivatives are used: glycine ethyl ester, glycinamide, alanine and its methyl ester, b -alanine methyl ester, a -amino-butyric ethyl ester, leucine methyl and ethyl esters, leucine diethylamide, serine methyl ester, phenylalanine methyl ester and amide, tryptophane methyl and ethyl esters, histidine methyl ester, proline and its ethyl ester, glycylglycine, glycylleucine methyl ester and diglycylglycine methyl ester. Specifications 480,822 and 573,514 are referred to.  According to the Specification as open to inspection under Sect. 91 the amino acid esters so obtained may be reacted with ammonia, amines or hydrazine to give the corresponding amides and hydrazides.  The latter may be converted into the azides which will then react with ammonia, amides or amino acid derivatives. Thus, tri- and poly-peptides may be built up.  This subject-matter does not appear in the Specification as accepted.
