실험 절차

The following is an adaptation of the method of Bringmann. A solution containing 4-bromo-1-naphthol (10.0 g, 0.045 mol), potassium carbonate (31 g, 0.224 mol), and 2-bromopropane (27.6 g, 0.224 mol) in DMF was heated at reflux for 1 h under a nitrogen atmosphere. The mixture was cooled to room temperature and the solvent was removed under reduced pressure. The resultant residue was subjected to silica gel chromatography using a 50% ethyl acetate-hexane mixture as the eluent to provide 4-isopropoxy-1-bromonaphthalene.
