実験手順

N-Iodosuccinimide (148.75 g, 0.661 mol) was added to a stirred solution of 2-butyl-4-hydroxymethylimidazole (100.78 g, 0.652 mol) in 500 mL of absolute ethanol. After 20 minutes the solution was heated to 40°-45° C. for 45 minutes, diluted with 2.5 liters of water, and chilled. The crystalline product was collected by filtration, washed with water, and dried to give 174.5 g (95%) of crystals; mp 166°-166.5° C.
