反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2,4,5-triiodo-1H-imidazole (165) (4.08 g, 9.1 mmol) in DMF (28 mL) at 0° C., was added NaH (1.46 g, 36.4 mmol) portionwise over 30 mins. Then 1-(2-iodoethyl)pyrrolidine×HI 164 (4.85 g, 13.65 mmol) was added at 0° C., and the reaction mixture was allowed to warm to room temperature over a period of 4 hrs. EtOAc (50 mL) was added and the mixture was washed with NaHCO3 aqueous solution. The organic phase was separated and extracted with citric acid solution (3%), the acidic aqueous extract was basified with 2N NaOH solution to pH˜10, the resultant solid was collected by filtration to give the title compound 166 (1.75 g, 35%) as a light brown solid. MS (m/z): 543.5 (M+H). the mixture was washed with NaHCO3 aqueous solution The organic phase was separated extracted with citric acid solution (3%) the acidic aqueous extract the resultant solid was collected by filtration
