Abstract
NEW MATERIAL:2,6-Dichloro-4-nitrodiphenylamine of formula I.
USE: An itermediate of 0-(2,6-dichloroanilinophenyl)acetic acid which is an anti- inflammatory agent or analgesic.
PREPARATION: A diazonium salt resulting from the diazotization of the amino group in 2,6-dichloro-4-introaniline of formula II is substituted with a halogen to form 2,6-dichloro-4-nitrohalobenzene of formula III (X is C1, Br or I). Then the product is subjected to the reaction with an excess amount of aniline in the presence of an alkali metal carbonate to prepare the objective compound of formula I.
