Related Products of 865156-59-8, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.865156-59-8, name is 4-Bromo-6-methylpyridin-2-ol, molecular formula is C6H6BrNO, molecular weight is 188.0219, as common compound, the synthetic route is as follows.
Diisopropyl diazocarboxylate (323 mg, 1.60 mmol) was added to a solution of 4- bromo-6-methylpyridin-2-ol (200 mg, 1.06 mmol), methanol (54 iL, 1.3 mmol) and triphenylphosphine (419 mg, 1.60 mmol) in THF (4.6 mL). The reaction mixture was stirred at r.t. for 18 h. Ethyl acetate was added and the mixture was washed with 1 N NaOH (3x). The organic layer was dried with sodium sulfate, filtered and evaporated under reduced pressure. The crude product was purified by flash chromatography on silica gel using a solution of ethyl acetate in hexanes (5 to 10%) to give the title compound (65 mg, 0.32 mmol, 30%).
The chemical industry reduces the impact on the environment during synthesis 865156-59-8, I believe this compound will play a more active role in future production and life.
