反应详情

A mixture of 30 g of 3-chloro-4-methoxyaniline, 18.9 g of 2,6-dichloro-3-nitrobenzoic acid, and 150 ml N,N-dimethylaniline was heated at 100° under nitrogen for 24 hours. The reaction mixture was dissolved in chloroform and washed with dilute ammonium hydroxide. After the aqueous layer was washed with chloroform, it was acidified and the resulting orange solid was collected to provide 6-chloro-2[(3-chloro-4-methoxyphenyl)amino]-3-nitrobenzoic acid, mp 222°-228° C.
