Abstract

Inventia se refera la derivati de 1,1'-oxibis-(4N-benzanzamido)-benzen, care au structura corespunzatoare formulei generale I: (VEZI FORMULA îN DESC.) în care R este H; 4-Cl; 4-CH3; 2-CH2, produse albe cristaline putin solubile în benten, etanol usor solubile în acetona si cloroform, insolubil în apa, cu puncte de topire în intervalul 162....192 degree C. Procedeul de preparare a derivatiilor consta în aceea ca un aminodifenileter cu formula generala II . (vezi form. în desc) în care R are semnificatiile de mai sus, se trateaza cu acidul 2,6-dimetoxibenzoic, în mediu de clorbenzen, la temperatura de reflux, în prezenta triclorurii de fosfor, în conditii anhidre.The invention relates to 1,1'-oxybis (4N-benzanzamido) -benzene derivatives having the structure corresponding to general formula I wherein R is H; 4-Cl; 4-CH3; 2-CH2, poorly soluble white crystalline white crystals in ethanol, water soluble insoluble ethanol and chloroform, with melting points in the range 162-192 ° C. The process for the preparation of derivatives consists in that an aminodifenileter with the general formula II. (where R is as defined above), treat with 2,6-dimethoxybenzoic acid in chlorobenzene at reflux temperature in the presence of phosphorus trichloride under anhydrous conditions.
