Procedure

To a round bottom flask was added methylthioninium chloride (MTC, Methylene Blue) (2 g, 6.25 mmol) and water (50 cm3) and the mixture stirred for 10 minutes or until the solid dissolved. Potassium iodide (1.56 g, 9.4 mmol) was then added to the mixture and a green black suspension formed. The reaction was heated to boiling and allowed to cool naturally giving the title compound (2.03 g, 79%) as bright green needles. Anal.
