实验步骤: 1.0 g (9.35 mmol) of 4-ethylpyridine and 1.86 g (9.35 mmol) of 4-methylphenethyl bromide were reacted in the same manner as in Example 1. The reaction product was purified to obtain 2.07 g of the desired compound (yield: 98.4%). The resulting compound was identified as 1-(4-methylphenyl)-3-(4-pyridyl)-butane (hereinafter referred to as compound 7) by the following analytical results. The reaction product was purified
