실험 절차

In the same system as described for the 2,6-dihydroxy analog, a solution of 0.01 mole of the silated 2-hydroxy-anthraquinone in tetrahydrofuran is treated slowly with a solution of 0.01 mole of the same lithio anion. The reaction is allowed to proceed for two hours at room temperature. This solution of the enamine is hydrolyzed at room temperature by addition of 20 ml. of 90% formic acid solution. The reaction mixture is filtered, washed with water, dried and recrystallized from toluene giving 2-hydroxy-9,10-anthracene dicarboxaldehyde.
