Procedure

Methyl-thioninium chloride (2.00 g, 6.25 mmol) was dissolved in water (50 cm3) and potassium iodide (1.56 g, 9.4 mmol) was added with stirring. A precipitate formed, which was filtered and the solid was recrystallised from boiling water (50 cm3) to yield the title compound (1.98 g, 77%) as fine green needles. δH (250 MHz; DMSO): 7.88 (2H, br d, ArH), 7.49 (4H, br s, ArH), 3.37 (12H, s, CH3). Analysis for C16H18N3SI: C, 46.72; H, 4.41; N, 10.22; S, 7.80; I, 30, 85. Found: C, 46.30; H, 4.21; N, 10.14; S, 7.86; I, 29.34.
