반응 단계
A reaction mixture of hydroquinone (18.2 grams); (S)-(+)-1-bromo-2-methylbutane (4.55 grams); anhydrous potassium carbonate (23 grams); and acetonitrile (250 mls.) was allowed to reflux for 40 hours. Flash chromatography using dichloromethane eluant yielded 2.6 grams (48%) of white crystals exhibiting a Fisher-Johns melting point of 44°-45° C. and having the structure ##STR24## confirmed by TLC, NMR, IR and mass spectral analyses.
