참여 물질

반응 단계

To a solution of 2-bromo-5-(2-ethoxyethoxy)-1,3-dimethylbenzene (10.0 g, 36.6 mmol) in tetrahydrofuran (100 mL) was added n-butyllithium hexane solution (1.6 M, 25.1 mL, 40.2 mmol) at −78° C. with stirring. The reaction mixture was stirred at the same temperature for 30 min. and triisopropyl borate (10.5 mL, 45.5 mmol) was added. The reaction mixture was warmed to room temperature and stirred for 3 hrs. 5 N Hydrochloric acid (20 mL) was added to the reaction mixture and the mixture was partitioned between ethyl acetate and water. The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The residue was washed with hexane/diethyl ether and dried to give the title compound (5.9 g, yield 68%) as pale-yellow crystals.
