Procedure

A solution of 2.66 g. (0.01 mole) of 2,6-dihydroxy-9,10-anthracenedicarboxaldehyde in 100 ml. of hot glacial acetic acid is treated with 2.5 g. (0.025 mole) of acetic anhydride. The mixture is stirred, heated on a steam for one hour, then allowed to cool yielding crystals of 2,6-diacetoxy-9,10-anthracenedicarboxaldehyde.
