Abstract

The invention comprises octahydro-indoloquinolines (ergolenes) of the formula <FORM:0774987/IV(b)/1> where R1 is C1-C8 alkyl, and acid additio salts thereof. These are made by the action of strong alkali on hexahydro-benzindoles of the formula <FORM:0774987/IV(b)/2> (see Specification 774,986), followed, if desired, by salt formation with the appropriate mineral acid. An example is given of the process where R1 is methyl, the product being obtained as hydrochloride. The strong alkali may be an alkali hydroxide or alkoxide. The alkyl group R1 may also be ethyl, propyl or n-heptyl. The products are intermediates in the synthesis of lysergic acid and its homologues.
