THIENYLAZOLYLALCOXYETHANAMINES, THEIR PREPARATION AND THEIR APPLICATION AS MEDICAMENTS

摘要

The thienylazolylalcoxyethanamines (I) wherein R1 is a hydrogen atom, a halogen or a lower alkyl radical; R2, R3 and R4 represent independently a hydrogen atom or a lower alkyl radical; and Az is a 5-member nitrogenated aromatic N-methyl substituted heterocycle which contains from one to three nitrogen atoms, have an analgesic activity in mammals, including human beings. The compounds (I) can be obtained for example by reacting a hydroxythienylazol derivative (IV) with a derivative of an appropriate N-(ethyl)amine. The compound (IV) are useful intermediates for the synthesis of the compounds (I). The compounds (I) can be applied to human and/or veterinary medicine.
