Reaction Steps
A mixture of 20 parts of 4-chloroanthraquinone-1-carboxylic acid, 200 parts of dimethylformamide and 3 parts of copper (I) oxide is heated for four hours at 150°C. The end product is precipitated by pouring the mixture into 400 parts of water and filtered. 14 parts (83.4% of theory) of 1-chloroanthraquinone is obtained having a melting point of 154° to 157°C.
