Reaction Steps

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