Reaction Steps

To 10.0 g of 4′-bromoacetophenone were added 12.8 g of iodine and 80 mL of pyridine and heated, and the mixture was stirred at 100° C. for 3 hours. After cooling to room temperature, 100 mL of water was added, and purification was performed by recrystallization. Drying was performed under reduced pressure at 70° C. for 12 hours to give 15.5 g (yield: 76%) of 4-bromophenacylpyridinium iodide as a brown powder.
