実験手順
1,3,5-Triiodo-2,4,6-trihydroxymethylbenzene (4.5 g, 8.2 mmol) was dissolved in DMSO (80 ml). Triethylamine (51.7 ml, 371 mmol) and pyridine.SO3 (11.8 g, 74.2 mmol) were added and the mixture was stirred for two hours. The two phases were separated and the lower phase was cooled to 0° C., poured into water (150 ml) and stirred for 30 min at 0° C. The white solid was collected by filtration, washed with water and dried. Yield: 3.0 g (67%).
