Application of 65515-39-1, 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. 65515-39-1, name is 2-Methoxy-4,6-dimethylnicotinonitrile. A new synthetic method of this compound is introduced below.
(a) 2-methoxy-6-methyl-4-(pent-4-en-l-yl)nicotinonitrile To a solution of 2-methoxy-4,6-dimethylnicotinonitrile (1.115 g, 6.87 mmol) in THF (20 mL) was added LiHMDS (1 M in toluene, 7.22 mL, 7.22 mmol) at 0 C dropwise via syringe over 10 min, and the reaction was stirred at this temperature for 1 h. 4- Bromobut-l-ene (0.733 mL, 7.22 mmol) was added dropwise via syringe and the mixture was stirred from 0 C to room temperature overnight. The reaction was poured into saturated aqueous ammonium chloride (50 mL) and extracted with EtOAc (3 x 75 mL). The combined organics were dried over Na2S04, filtered, concentrated, and the residue purified by flash chromatography (0-20% EtOAc in hexanes, 40-g column, product fractions pooled and recolumned 0-10% EtOAc in hexanes, 40-g column) to afford 2- methoxy-6-methyl-4-(pent-4-en-l-yl)nicotinonitrile (619 mg, 42%) as a colorless oil. LC- MS(ES) m/z = 217 [M+H]+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,65515-39-1, its application will become more common.
