Synthetic Route of 1206775-52-1, 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.1206775-52-1, name is 5-Bromo-6-methoxypicolinaldehyde, molecular formula is C7H6BrNO2, molecular weight is 216.032, as common compound, the synthetic route is as follows.
5-Bromo-6-methoxypyridine-2-carboxaldehyde (15 g, 69.3 mmol, 1 eq.) Was dissolved in 300 ml of dichloromethane, and the temperature was lowered to -78 C. Under nitrogen protection, diethylaminosulfur trifluoride (44.7 g, 277.2 mmol, 4 eq.) Was added dropwise. After completion of the dropwise addition, the reaction was carried out at 18 C for 18 hours.After the reaction was completed, the reaction solution was dropped into ice water and made alkaline with a saturated sodium bicarbonate solution. Extraction with dichloromethane, concentration of the organic phase and column chromatography gave 15 g of 3-bromo-6- (difluoromethyl) -2-methoxypyridine as a white solid with a yield of 91%.
Statistics shows that 1206775-52-1 is playing an increasingly important role. we look forward to future research findings about 5-Bromo-6-methoxypicolinaldehyde.
