New downstream synthetic route of 39774-26-0

At the same time, in my other blogs, there are other synthetic methods of this type of compound,39774-26-0, 2-Bromo-6-phenylpyridine, and friends who are interested can also refer to it.

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.39774-26-0, name is 2-Bromo-6-phenylpyridine, molecular formula is C11H8BrN, molecular weight is 234.09, as common compound, the synthetic route is as follows.Application In Synthesis of 2-Bromo-6-phenylpyridine

To a solution of 21-1 (2.70 g, mixture from previous step) in tetrahydrofuran (50 mL) cooled to -78 C. under nitrogen, n-butyllithium (2.5 M in hexanes, 5.8 mL, 14.5 mmol) was added dropwise. The mixture was stirred for 45 minutes then N,N-dimethylformamide (1.80 mL, 23 mmol) was added. The mixture was stirred at -78 C. for 1 hour, warmed to room temperature, quenched with water, and extracted with ethyl acetate. The organic layer was washed three times with water, once with brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by silica gel column chromatography, eluting with 2.5% followed by 5% ethyl acetate in hexanes to give 6-phenylpicolinaldehyde (21-2, 1.24 g) as a yellow oil.
