Procedimiento

A 10 g. portion of 3-(3-bromophenyl)-1-methyl-5-phenyl-4(1H)-pyridinone was made from 22 g. of the corresponding 2-propanone as described in Example 1. A 3.4 g. portion of the intermediate pyridinone was dissolved in chloroform and 1.8 g. of methyl trifluoromethanesulfonate was added. The reaction mixture was allowed to stand overnight, and the volatile portions were then evaporated under vacuum. The residue was identified as 3-(3-bromophenyl)-4-methoxy-1-methyl-5-phenylpyridinium trifluoromethanesulfonate, molecular weight 339 by mass spectroscopy.
