Procedure
The procedure of Example 41 was repeated with the exception that 3.5 g of benzyl acetone in place of cinnamic aldehyde and 2.26 g of 3-ethyl-4-methylpyridine were used in Example 41, to obtain 3.26 g (yield: 59.8%) of (E)-1-(3-ethyl-4-pyridyl)-2-methyl-4-phenyl -1-butene (hereinafter referred to as compound 55) and o.95 g (yield: 17.4%) of (Z)-1-(3-ethyl-4-pyridyl)-2-methyl-4-phenyl-1-butene (hereinafter referred to as compound 56). The analytical results are shown below.
