実験手順

Using 3.5 g (13.8 mmol) of 4-trifluoromethoxy-4'-hydroxybiphenyl, 45 ml of acetonitrile, 2.01 g (14.5 mmol) of 3-bromo-1-propanol and 3.81 g (27.5 mmol) of anhydrous potassium carbonate, synthetic treatment was carried out in the same manner as in Example 2. The obtained gray powder was recrystallized from benzene/n-hexane to obtain 3.52 g (yield: 82%) of 4-trifluoromethoxy-4'-(3-hydroxypropoxy)biphenyl (21) as a colorless powder.
