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. 1620-76-4, name is 4-Methylpicolinonitrile, the common compound, a new synthetic route is introduced below. HPLC of Formula: C7H6N2
Reference Example 55 4-Methyl-2-pyridinecarbaldehyde diisobutyl aluminium hydride in toluene (1.5 M, 43.5 ml, 65 mmol) was added dropwise to a solution of 2-cyano-4-methylpyridine (7.0 g, 59 mmol) in dichloromethane (180 ml) at -78 C, and the mixture was stirred at the same temperature for 2 hrs.. The reaction mixture was combined with concentrated hydrochloric acid (28 ml) and water (112 ml), and the water layer and the organic layer were separated.. The organic layer was extracted with 2 N hydrochloric acid.. The water layer was combined, neutralized with sodium hydrogen carbonate and extracted with diethyl ether.. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate.. The solvent was evaporated to give the titled compound (2.7 g, 37 %).
The synthetic route of 1620-76-4 has been constantly updated, and we look forward to future research findings.
