摘要:
The present invention relates to novel, antiarrhythmically active phenoxyalkylamine derivatives possessing a double point of attack. More particularly, the present invention relates to new phenoxyalkylamine derivatives of the formula (1) wherein R1 and R2, independently from each other, mean hydrogen, halogen or C1-4 alkyl group; R3, R4 and R5, independently from each other, stand for hydrogen or C1-4 alkyl group; R6 represents hydrogen, C1-4 alkyl or benzyl group; R7 means nitro group or amino group optionally monosubstituted by C1-4 alkyl, benzoyl, C1-4 alkylcarbonyl, C1-4 alkylsulfonyl, C1-4 alkylcarbamoyl or C1-4 alkylthiocarbamoyl group; both n and m are 0 or 1, with the proviso that R2 is different from hydrogen, when R1 is hydrogen, as well as stereoisomers or mixtures of stereoisomers thereof, acid addition salts thereof and hydrates, prodrugs and metabolites of all these compounds.

The invention relates to new 8.beta.-hydrazinomethyl-ergoline derivatives of the general formula (I), ##STR1## wherein x y stands for a ##STR2## or ##STR3## group, R stands for hydrogen or methyl group, andR.sub.1 stands for hydrogen, a lower acyl group, a di-(lower-alkylaminocarbonyl group, a group of the general formula (VI), ##STR4## wherein Z.sub.1, Z.sub.2 and Z.sub.3 each represent hydrogen, halogen or a trifluoromethyl group, or a group of the general formula (VII), ##STR5## wherein Y represents a lower alkyl group, allyl group or phenyl group, and acid addition salts thereof. These compounds possess valuable antiserotonine, antidepressant and hypotensive effects, furthermore they can be applied as starting substances in the preparation of other biologically active ergoline derivatives.The new compounds of the general formula (I) are prepared according to the invention by reacting the respective 6-methyl-8.beta.-mesyloxymethyl or -tosyloxymethyl-ergoline derivatives with dry hydrazine. In order to obtain the N-substituted hydrazinomethyl compounds, the N-unsubstituted derivatives are reacted with an acylating agent or with an isothiocyanate.
