Abstract

Predmetni pronalazak je usmeren na postupke za pripremanje jedinjenja koja sadrže prsten piperazina, a posebno na mirtazapin. Prema predmetnom pronalasku, intermedijer mirtazapina, 1-(3-karboksipiridil-2)-4-metil-2-fenil-piperazin se dobija hidrolizom 1-(3-cijanopiridil-2)-4-metil-2-fenil-piperazina pomoću baze, pri čemu je baza prisutna u odnosu koji se kreće do oko 12 molova baze na jedan mol 1-(3-cijanopiridil-2)-4-metil-2-fenil-piperazina. Intermedijer mirtazapina, 1-(3-karboksipiridil-2)-4-metil-2-fenil-piperazin, može se dobiti hidrolizom 1-(3-cijanopiridil-2)-4-metil-2-fenil-piperazina pomoću kalijum-hidroksida pri temperaturi od oko bar 130В°C. Postupak predmetnog pronalaska takodje obuhvata reakciju 2-amino-3-hidroksimetil piridina sa N-metil-1-fenil-2,2'-iminodietil hloridom, kako bi se dobio 1-(3-hidroksimetilpiridil-2)-4-metil-2-fenil piperazin, kao i dodavanje sumporne kiseline 1-(3-hidroksimetilpiridil-2)-4-metil-2-fenil piperazinu, kako bi se dobio mirtazapin. Predmetni pronalazak se takodje odnosi na nove postupke za rekristalizaciju mirtazapina iz sirovog mirtazapina.
