Reference example 3 2-chloro-4-methoxyboronic acid A solution of 3-chloro-4-bromoanisole (2.14 g) in anhydrous tetrahydrofuran (10 ml) was cooled at -78§C. 1.56 M n-butyl lithium / hexane (6.5 ml) was dropped into the solution, and the mixture was stirred for 30 minutes. Triisopropyl borate (2.3 ml) was dropped into the reaction mixture, and the mixture was stirred for 2 hours at -78§C. A saturated aqueous solution of ammonium chloride was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous sodium sulfate and concentrated. A obtained solid was washed with t-butyl methyl ether (4 ml), filtered and dried over to give the title compound (681 mg) having the following physical data. TLC: Rf 0.55 (methylene chloride: methanol = 19: 1); NMR (300MHz, CDCl3): delta 7.22 (d, J = 8.4Hz, 1H), 6.93 (d, J = 2.4Hz, 1H), 6.86 (dd, J = 8.4, 2.4Hz, 1H), 3.79 (s, 3H). |
