O-Cresol → 4-[1-(4-Bromophenyl)-1-ethylpropyl]-2-methylphenol

Participants

Reaction Steps

o-Cresol (890 mg, 8.23 mmol) was added to a solution of 3-(4-bromo-phenyl)-pentan-3-ol (Example 143-(1); 2.0 g, 8.23 mmol) in trifluoroacetic acid (20 mL), and the mixture was stirred at room temperature for five hours. Then, the reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (hexane:ethyl acetate=100:0 to 30:70) to give the target compound as a colorless oil (2.59 g, 94%).
