In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 20970-75-6, name is 2-Cyano-3-methylpyridine, the common compound, a new synthetic route is introduced below. Product Details of 20970-75-6

General procedure: To a 25 mL round-bottom flask equipped with magnetic stirrer were added nitrile (2 mmol), acetaldoxime (6 mmol), sodium molybdate (VI) dihydrate (0.2 mmol) and H2O (10 mL). The mixture was heated to reflux for 5-16 h. After cooling to room temperature, the solution was directly evaporated to dryness and the residue was purified by column chromatography on silica gel (ethylacetate/n-hexane) to give the corresponding amide.

The synthetic route of 20970-75-6 has been constantly updated, and we look forward to future research findings.

Synthetic Route of 20970-75-6, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 20970-75-6, name is 2-Cyano-3-methylpyridine, molecular formula is C7H6N2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

EXAMPLE 1; 3-Cycloheptyl-8-((2,6-dichlorophenoxy)methyl)H-imidazo[1,5-a]pyridine; Compound 1A: 3-(Bromomethyl)picolinonitrile To a solution of 3-methylpicolinonitrile (660 mg, 5.6 mmol) in 20 mL of carbon tetrachloride was added NBS (1 g, 5.6 mmol) and dibenzoyl peroxide (200 mg, 0.83 mmol) at RT. The reaction mixture was heated at 80 C. for 2 hr, and then cooled to RT. The resulting solid was filtered off, and the filtrate was concentrated under reduced pressure to provide a residue. The residue was diluted with ethyl acetate, washed with water, dried over Na2SO4 and concentrated under reduced pressure to provide crude material. The crude material was purified via silica gel chromatography (10% ethyl acetate in hexanes) to provide compound 1A (510 mg, 46%) as a pale yellow oil. HPLC Rt (Method A): 1.72 min. LC/MS (m/z)=197 (M+H)+.

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 20970-75-6, 2-Cyano-3-methylpyridine.
