반응 단계

1,9-Dimethylphenothiazine (4.2026 g, 18.49 mmol) was dissolved in 130 mL of chloroform and crushed iodine (14.1 g, 55.55 mmol, 3 eq.) dissolved in 520 mL of chloroform was added over 2 hurs. Once newly formed precipitate was filtered off or the solvent removed under vacuum, the resulting iodide salt was stirred with ether or hexane (sometimes overnight) to remove excess iodine then refiltered. After pumping down under vacuum, a brown precipitate was obtained as product (12.6 g).
