Abstract
Inventia se refera la un procedeu pentru prepararea unor derivati ai acidului 7 beta-aminotiazolilacetamido-3-cefem-4-carboxilic cu formula generala I: (vezi formula) în care A reprezinta o grupa metilen, eventual substituita cu o grupa amino, hidroximino, metoxiimino sau N-metilcarbamoiloxiimino, R1 reprezinta hidrogen, pivaloiloximetil, p-nitrobenzil sau difenil metil, iar R2 reprezinta hidrogen sau o grupa metoxi, procedeu în care un compus cu formula generala II: (vezi formula) în care X reprezinta un atom de halogen si R1, R2 si A au semnificatiile de mai sus, se condenseaza cu tiouree sau o sare a acesteia, la temperatura camerei, folosind ca solvent dioxanul, dupa care în cazul în care R1 reprezinta o grupa carboxiprotectoare aceasta este înlocuita cu hidrogen, prin metode în sine cunoscute si/sau daca se doreste compusul obtinut se transforma într-o sare a sa acceptabila farmaceutic.
