Nitric esters of 2-(2,6-dihalophenylamino) phenylacetoxyacetic acid derivatives and their preparation process

摘要

Nitric esters of 2-(2,6-dihalophenylamino) phenylacetoxyacetic acid derivatives with the formula (I), where: ÄA IDENTICAL F, Cl or Br; X IDENTICAL O, NH or NR (R IDENTICAL C1 - C8 alkyl); R1 and R2 independently IDENTICAL C1 - C8 alkyl and n is a whole number from 1 to 10. The procedure includes the condensation of 2-(2,6-diahlophenylamino) phenylacetoxyacetic acid with a compound with the formula: <CHEM> where Y IDENTICAL OH, NH2 or NHR and Z is Cl, Br or ONO2.a
