Abstract
Inventia se refera la un procedeu de preparare a unor derivati de piridina cu formula generala I: (vezi formula) în care R1 este o grupa metil, fenil, sau OCON(CH3)2, R2 este hidrogen sau o grupa metoxi, R3 este hidrogen o grua metil, sau OCON(CH3)2, R4 este hidrogen si R5 hidrogen sau metil, sau R4 si R5 împreuna formeaza o grupa (vezi formula) este hidrogen, clor, brom, metil, metoxi, difluormetoxi sau fenoxi, sau este o grupa (vezi formula) în care R7 este o grupa metil, izopropil, metoxi sau fenoxi, prin oxidarea unui derivat de piridina nesubstituit la azot si care are substituentii R1...R5, cu acid 3-clorperbenzoic în mdeiu de cloroform sau acid acetic glacial, raportul în greutate între reactanti fiind de 1:0,8...1,2 la temperatura de 0...8 degree C, dupa care amestecul de reactie este prelucrat, în mod cunoscut, pentru separarea produsului.
