2,6-Dimethylphenol → 4-[1-(4-Bromo-3-methyl-phenyl)-1-ethyl-propyl]-2,6-dimethyl-phenol

Participants

Reaction Steps

2,6-Dimethylphenol (950 mg, 7.78 mmol) was added to a solution of 3-(4-bromo-3-methyl-phenyl)-pentan-3-ol (Example 38-(1); 2.0 g, 7.78 mmol) in trifluoroacetic acid (20 mL), and the mixture was stirred at room temperature for two 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 50:50) to give the target compound as a colorless oil (2.62 g, 93%).
