実験手順

2.25 g of 1,2-dimethyl-10-(3-aminopropyl)phenothiazine-5-oxide synthesized in Example 8, 990 mg of bromoacetonitrile and 1.2 g of potassium carbonate were dissolved in 50 ml of N,N-dimethylformamide followed by stirring at 80° C. for 10 min. Then the reaction mixture was cooled to room temperature and, after adding water, extracted with ethyl acetate. The organic layer was washed with brine and dried over anhydrous magnesium sulfate. After evaporating the solvent under reduced pressure, the residue was purified by silica gel column chromatography to give 670 mg of the title compound.
