Electric Literature of 59105-50-9, 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.59105-50-9, name is (5-Bromopyridin-3-yl)(phenyl)methanone, molecular formula is C12H8BrNO, molecular weight is 262.1, as common compound, the synthetic route is as follows.

General procedure: Pd(PPh3)4 (17.3 mg, 0.015 mmol) was added to a solution of 3-benzoy-5-bromo pyridine(130.1 mg, 0.5 mmol) and aryl boronic acid (0.6 mmol) in MeOH (0.2 mL), toluene (0.8 mL),and 2 M Na2CO3 (0.2mL) under N2. The mixture was heated to 75 C for 2 h, and then cooledto room temperature and concentrated under reduced pressure. Water was added to theresidue and the aq. phase was extracted with DCM (3 × 5 mL). The combined organic layerswere washed with brine, dried over Na2SO4, and evaporated to obtain the crude product.Purification by column chromatography on silica gel afforded the desired product.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 59105-50-9, name is (5-Bromopyridin-3-yl)(phenyl)methanone. A new synthetic method of this compound is introduced below., Computed Properties of C12H8BrNO

(1S,4S)-5-(5-Benzoyl-3-pyridyl)-2-(tert-butoxycarbonyl)-2,5-diazabicyclo[2.2.1]heptane In a sealed pressure tube under a nitrogen atmosphere, 3-benzoyl-5-bromopyridine (0.542 g, 2.1 mmol), (1S,4S)-N-(tert-butoxycarb- onyl)-2,5-diazabicyclo[2.2.1]heptane (0.475 g, 2.4 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.04 g, 0.04 mmol), rac-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (0.05 g, 0.08 mmol), sodium tert-butoxide (0.380 g, 3.8 mmol) and anhydrous toluene (20 mL) were stirred at 90 C. for 20 h. The reaction mixture was cooled to room temperature and diluted with water (200 mL) and then extracted with diethyl ether (100 mL). The diethyl ether extract was dried (MgSO4), filtered and concentrated by rotary evaporation. The residue was purified by flash chromatography on silica gel, using a gradient of 50% to 80% ethyl acetate:hexane as eluent, to yield 0.364 g (48%) of a yellow oil.
