실험 절차

Potassium tert-butoxide (800 mg) was added to a solution of 12-acetyl-5-hydroxy-12H-benzo[a]phenothiazine (950 mg) (from Example 3) and methyl iodide (1.5 ml) in DMF (10 ml) and stirred for 15 minutes. Water (80 ml) was added to the reaction mixture and the precipitate was filtered to afford the title compound.
