Electric Literature of 16932-49-3, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 16932-49-3, name is 2,6-Dimethoxybenzonitrile, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: :2,6-dimethoxybenzonitrile (501 mg, 3.07 mmol) and4-amino-7-chloroquinoline (548 mg, 3.07 mmol) were dissolved together in 20 mLof anhydrous tetrahydrofuran. The vesselwas swept with nitrogen and chilled in an ice-water bath. Ethereal 3.0 M ethyl magnesium bromide (2.05 mL,6.14 mmol) was added dropwise over 3 min.After briefly forming an off-white solid suspended in a yellow solution,within minutes the mixture became a dark amber homogenous solution with someoff-white solid material remaining. Thevessel was placed in a 75 C oil bath for 21 h before diluting with 60 mL ofwater. The pH was decreased to ca. 14 byaddition of 4 pellets of NaOH. Themixture was then extracted with 60 mL of ethyl acetate, using solid NaCl tofacilitate partitioning. The organicswere dried over MgSO4 and concentrated to 1.27 g of a crude brownoily paste containing mostly unreacted starting materials. Flash chromatography (150 mL silica gel, 50%ethyl acetate / hexane, then neat ethyl acetate, then 10% methanol in ethylacetate) returned 100 mg (9.6%) ofN-(7-chloroquinolin-4-yl)-2,6-dimethoxybenzimidamide (G).
The chemical industry reduces the impact on the environment during synthesis 2,6-Dimethoxybenzonitrile. I believe this compound will play a more active role in future production and life.
