Abstract
The invention comprises compounds of the general formula <FORM:0994486/C2/1> wherein R1 represents a C1- 4 alkyl radical, a C2- 4 alkenyl radical or a C7- 10 aralkyl radical, R2 represents a C3- 8 cycloalkyl radical or a C7- 10 aralkyl radical and R3 represents a hydrogen atom, a C1- 6 alkyl or hydroxyalkyl radical, a C3- 8 cycloalkyl radical or a C7- 10 aralkyl radical, but R2 and R3 do not both represent cycloalkyl or aralkyl radicals, or R2 and R3 together represent a C5 alkylene radical, and \sG represents <FORM:0994486/C2/2> and their acid addition salts, and the preparation of compounds of formula I (and their acid addition salts) wherein R2 may additionally represent a hydrogen atom (when R3 is other than hydrogen), a C1- 6 hydroxyalkyl radical (when R3 is other than hydroxyalkyl) or a C1- 6 alkyl radical and R2 and R3 together may additionally represent a C4 alkylene radical, by reacting an alkali metal salt of the corresponding carboxylic acid with sulphur trioxide and reacting the product with an amine R2NHR3, or by converting the hydrazide of such acid into the corresponding azide and reacting this with said amine, and in either case, if desired, converting the product into an addition salt with an inorganic or organic acid. 1 - R1 - Lysergic and - 9,10 - dihydrolysergic acids and their hydrazides are prepared by introducing the desired substituent R1 into the 1-position of an ergot alkaloid (especially one that is therapeutically useless) and subjecting the product (if necessary after hydrogenation in the 9,10-position) to heating with barium hydroxide in alcohol (followed by precipitation of barium ions with sulphuric acid) or to reaction with hydrazine (one or both of the reactants preferably being in the form of an acid addition salt in the case of the non-hydrogenated compounds). 1-Alkyl-D-lysergic acid is prepared by reacting D-lysergic acid with sodamide and allyl bromide. Pharmaceutical compositions, suitable for inhibiting the action of serotonin and for treating psychic illnesses, comprise compounds I (or salts) as first defined above, together with a physiologically acceptable carrier.
