실험 절차

A mixture of 4-isopropyl-2-methoxybiphenyl (3.8g from Example 5) in aqueous hydrobromic acid (150ml; 48%) and acetic acid (glacial, 50ml) was stirred under reflux for 7 hours. The mixture was cooled, diluted with water and extracted with ether. The extract was washed with water, dried, evaporated and distilled to give 2-hydroxy-4-isopropylbiphenyl, b.p. 112°-113°/0.2 mm.
