Abstract
Inventia se refera la un procedeu pentru prepararea unor derivati de oxadiazol cu formula generala I: (vezi descriere), în care R1 si R2 sunt radicali alchil inferiori si R este un atom de halogen, un radical alcoxi sau haloalcoxi. Procedeul consta în aceea ca se trateaza compusi cu formula generala II: (vezi descriere), cu un compus cu formula generala III: (vezi descriere), în care R, R1, R2 au semnificatiile de mai sus.The invention relates to a process for the preparation of oxadiazole derivatives of the general formula I: (wherein R 1 and R 2 are lower alkyl radicals and R is a halogen atom, an alkoxy or haloalkoxy radical). The process consists in treating compounds of the general formula II: (see description) with a compound of the general formula III: wherein R, R1, R2 are as defined above.
