ABSTRACT:
3,5-Dichloroaniline is advantageously produced by reacting 1-bromo-2,4-dichlorobenzene with a metal amide in liquid ammonia at a molar ratio of 1-bromo-2,4-dichlorobenzene to the metal amide of 1 : 2 to 7.
The 3,5-dichloroaniline is useful as an intermediate for various agricultural chemicals, dyes and medicines.
