실험 절차

4-Bromo-2-isopropylphenol (897 mg, 4.17 mmol) was dissolved in DMF (4.17 mL) and 4-bromo-2-methylbut-1-ene (1.24 g, 8.34 mmol) was added followed by K2CO3 (1.15 g, 8.34 mmol). The reaction mixture was heated to 60° C. overnight, cooled to room temperature, and diluted with Hexanes:EtOAc (1:1). Water was added and the organic layer was separated, dried over Na2SO4, filtered, and concentrated under vacuum. The crude residue was purified by silica gel chromatography, eluting with 0-15% EtOAc/Hexanes to give the title compound as a colorless oil.
