Participants

Reaction Steps

First, 695 mg of 2,2'-ethylenebis[2-(3-dimethylaminopropyl)-m-dithian] was dissolved in 24 ml of absolute methanol and 6 ml of absolute tetrahydrofuran, and after adding dropwise a solution of 3.12 g of thallium (III) nitrate trihydrate in 18 ml of absolute methanol over 2 minutes while stirring at a room temperature, the mixture was stirred for 30 minutes, filtered to remove insoluble matter, and evaporated under a reduced pressure to remove the solvent. After adding 30 ml of water, the mixture was extracted with 100 ml and 50 ml of chloroform. The extracts were combined, washed with a saturated sodium chloride aqueous solution, dried over magnesium sulfate, filtered, and evaporated under a reduced pressure. The residue was applied to a silica gel column and eluted with chloroform/methanol/triethylamine (80:20:1) to obtain 178 mg of the title compound as a pale yellow liquid.
