The invention relates to the new compounds: <IMAGE> in which R1 is a (C1-C5)alkyl, R2 is H or (C1-C5)alkyl, A is a chain (CH2)n, n being an integer from 0 to 5, or -CH2-O- or an alkylene chain substituted by an alkyl, having a total of 2 to 8 carbon atoms, Z is a phenyl optionally substituted by a naphthyl, an indenyl, a heteromonocycle having 5 or 6 members or a heterobicycle, all these radicals being optionally substituted, it being understood that when Z represents a phenyl which is substituted in the ortho position by an alkoxy, A cannot represent (CH2)n in which n = 0, in all their possible enantiomeric and diastereoisomeric forms and in the form of addition salts with acids or of quaternary ammonium salts, to the process for their preparation and to the preparation intermediates, to their application as medicaments and to the compositions which contain them.
