Into a 200 ml flask, 7.82 g (41.1 mmol) of 4-hydroxybiphenyl, 83 ml of ethanol, 6 g (43.2 mmol) of 3-bromo-1-propanol and a NaOH aqueous solution (1.73 g (43.2 mmol) of NaOH/6 ml of water) were sequentially added, and the mixture was heated and refluxed for 6.5 hours. To the reaction solution, 50 ml of water was added, whereupon precipitated crystals were collected by filtration and recrystallized from ethanol to obtain 4.0 g (yield: 43%) of 4-(3-hydroxypropoxy)biphenyl (1) as a colorless powder.
