Abstract
PURPOSE: To obtain the title compound useful as a raw material through an easy preparation of Diclofenac, a nonsteroid analgic antiphlogistica, by reacting N,N- disubstituted-O-bromophenylacetamide derivative with 2,6-dichloroaniline in the presence of a cupric catalyst.
CONSTITUTION: An N,N-disubstituted-O-bromophenylacetamide derivative shown by the formula I (R1 and R2 are lower alkyl; R1 and R2 link together with N and/or O to form a heterocyclic ring) is reacted with 2,6-dichloroaniline in the presence of a cupric catalyst, e.g., CuBr2 [and, if necessary, an deoxidizer (e.g., an alkali metal carbonate, etc.] and a cocatalyst of NaI in a solvent, e.g., chlorobenzene at a temperature not lower than 80°C to give the title compound shown by the formula II.
EFFECT: The title compound is obtained from low-priced raw materials in extremely few steps in high yields in all processes and the procedures are simple. The compound is very safe and has a good crystallizability.
