(2-甲基吡啶-3-基)硼酸 - Reference Information
| Application | 2-methylpyridine-3-boronic acid is an organic intermediate, it can be prepared from 3-bromo-2-methylpyridine and triisopropyl borate in one step. 2-methylpyridine-3-boronic acid can be used to participate in the Suzuki reaction. |
| preparation | to 3-bromo-2-methylpyridine (4.00g,23 mmol) at -78°C butyl lithium (17mL,28 mmol) was added dropwise to a solution of triisopropyl borate (6.40 mL,28 mmol) and 50 mL/1 toluene/THF(4/1,50 mL). The mixture was heated to -70 °c over 30 minutes and then to 20 °c. HCl(2m) was added to bring the solution to pH 1. Water (20ml) was then added and the mixture was extracted with toluene. The aqueous layer was neutralized with 1M NaOH and extracted with dichloromethane. The aqueous layer was concentrated to dryness and the white solid was washed with dichloromethane. The combined organic layers were dried over sodium sulfate, filtered and concentrated to give 2.10g of 2-methylpyridine-3-boronic acid as a yellow oil. ES = 138.2(M H). |
