Abstract

Inventia prezinta un procedeu de preparare a unor derivati de piridoxina cu formula generala I: (vezi formula) în care R reprezinta un radical (vezi formula) în care n este 1, X si X1 sunt diferiti si reprezinta hidrogen sau metil si R1 reprezinta o grupa fenil sau fenil mono sau disubstituit cu fluor, clor, brom, metil, etil, n-propil, izopropil si metoxi, constînd din aceea ca 3-0-(2,3-epoxipropil)-alfa, alfa-izopropilidenpiridoxolul cu formula II: (vezi formula) se trateaza la reflux si în metanol ca solvent, cu o amina cu formula generala III: (vezi formula) în care R are semnificatiile de mai sus, pentru a obtine un cetal care apoi este hidrolizat în mediu puternic acid, la o temperatura cuprinsa între 25 si 80 degree C pentru a obtine derivatul de piridoxina I sub forma de baza libera, care, eventual, poate fi transformat prin tratare cu un acid organic sau anorganic adecvat în sarea de aditie netoxica.
