Procedure

N-phenacylpyridinium bromide was prepared by slowly adding phenacyl bromide to a stirred flask containing an equimolar quantity of pyridine. The slightly exothermic reaction was accompanied by the precipitation of the solid N-phenacylpyridinium bromide. The salt was then filtered and washed thoroughly with anhydrous ether.
