実験手順: 7.0 g of 5,5-diphenyl-2-thiohydantoin is dissolved in 50 ml of ethanol and 10 ml of 3N sodium carbonate added followed by 3 ml of iodomethane. The mixture is refluxed for 18 hours, then cooled and the solvent evaporated. The residual solid is recrystallized from ethanol to give 4.6 g (60%) of the title compound. The mixture is refluxed for 18 hours cooled the solvent evaporated The residual solid is recrystallized from ethanol
