N,N-Dimethylaniline → 1,6-dichloro-7-methoxy-4-nitro-9(10H)-acridinone

Participants

Reaction Steps

A mixture of 17 g of 6-chloro-2-[(3-chloro-4-methoxyphenyl)amino]-3-nitrobenzoic acid, 35 ml of phosphorus oxychloride, 1 ml of N,N-dimethylaniline and 150 ml 1,2-dichloroethane was heated under reflux for 45 minutes. The resulting solid was collected by filtration from the hot reaction mixture and was washed with chloroform to provide 1,6-dichloro-7-methoxy-4-nitro-9(10H)-acridinone, mp 284°-285° C.
