Abstract

Inventia se refera la un procedeu de preparare a unor derivati ai piridinei, cu formula generala I: (vezi formula) în care R1 si R2 sînt identici sau diferiti si reprezinta o grupa alchil inferioara sau, împreuna atomul de azot alturat, formeaza o grupa piperidino, R3 este hidrogen sau alchil inferior, caracterizat prin aceea ca un compus cu formula generala II. (vezi formula) în care R1 si R2 au semnificatiile de mai sus si L reprezinta un radical tioalchil cu 1...6 atomi de carbon, se trateaza cu o hidrazina cu formula generala R3NHNH2 în care R3 are semnificatiile de mai sus, cu formarea si ciclizarea în situ a compusului cu formula generala IV: (vezi formula) în care R1, R2 si R3 au semnificatiile de mai sus, reactia avînd loc în prezenta unui solvent, ales dintre o hidrocarbura aromatica, un alcanol cu 1...6 atomi de carbon apa, dietileter si dimetilformaldehida si la o temperatura cuprinsa între temperatura camerei si temperatura de reflux a amestecului de reactie, dupa care compusul cu formula I obtinut poate fi transformat într-o sare acceptabila farmaceutic, prin metode cunoscute.
