1-amino-2-chloroanthracene-9,10-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 1-amino-2-chloroanthraquinone (2.6 grams; 0.01 mole) and methyl fluorosulfonate (1.254 grams; 0.011 mole) in toluene (50 mls) was refluxed for 22 hours and filtered while hot. The residue in the flask was combined with the filter cake and the combined solids were slurried in 5 N sodium hydroxide at 25° C. for 0.5 hour. The slurry was then filtered, and the solid was rinsed with water and dried. The yield of product obtained was 41% of theoretical. filtered while hot The slurry was then filtered the solid was rinsed with water dried The yield of product obtained
