The invention provides novel compounds of the formula: <CHEM> wherein each of R1, R2 and R3, which can be the same or different, is hydrogen, chloro, bromo, fluoro, methyl, ethyl, methoxy, amino, hydroxy or nitro; R4 and R5, which can be the same or different, are hydrogen, an alkyl radical of 1 to 7 carbon atoms, hydroxymethyl or <CHEM> R6 is hydrogen, an alkyl radical of 1 to 7 carbon atoms or <CHEM> R7 and R8 are hydrogen, chloro or methyl; X is -CH=CH- or CHR9; R9 is hydrogen or hydroxy; n is 0-7 and m is 0-6; and their non-toxic pharmaceutically acceptable acid addition salts and mixtures thereof. Processes for the preparation of these compounds are described, as are novel pharmaceutical compositions comprising at least one of the compounds and their salts. The compounds and their non-toxic salts exhibit valuable pharmacological activity and are useful in the treatment of mammals, especially as antihypertensives and also as antithrombotic and antimycotic agents. |
