実験手順
4-isopropyl-benzene-1,3-diol (IMO-a: 9.13 g, 60 mmol) and benzyltrimethyl ammoniumtribromide (24.6 g, 63 mmol) and methylene chloride 250 mL were placed in a 500 mL three-neck flask and were stirred at room temperature for 4 hours. After the reaction was finished, the reaction mixture was washed twice with saturated ammonium chloride and once with saturated sodium chloride, and then dried over anhydrous sodium sulfate. After filtration and evaporation, the residue was purified by silica gel column chromatography to obtain the title compound (IM1-a: 10.5 g, 76%).
