実験手順

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 Examples 1-3. The pyridinone was reduced with 2 g. of lithium aluminum hydride as described in the examples above, and the reaction mixture was chromatographed as described above with benzene-ethyl acetate mixtures. The combined yield of the compounds of Examples 13 and 13a was 4 g., molecular weight 341 by mass spectroscopy. The yield of the compound of Example 14 was 0.5 g., molecular weight by mass spectroscopy 343.
