process for the preparation of n - (2,6 - diclorofenil) - n - feniln - (cloroacetil) - amine

摘要

N-(2,6-dichlorophenyl)-N-phenyl-N-(chloroacetyl)-amine of formula (I) (intermediate for the synthesis of Diclofenac) is prepared by means of rearrangement of N-(2,6-dichlorophenoxyacetyl)-aniline to give N-(2,6-dichlorophenyl)-aniline which, in its turn, is transformed into the final product by reaction with chloroacetyl chloride.
