Adding a certain compound to certain chemical reactions, such as: 97004-04-1, (6-Chloropyridin-3-yl)methanamine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: (6-Chloropyridin-3-yl)methanamine, blongs to pyridine-derivatives compound. Recommanded Product: (6-Chloropyridin-3-yl)methanamine
A mixture of 3-ethoxy-2-(4-trifluoromethylphenyl hydrazono) propionic acid (0.3 g, 1 mmol), 5-aminomethyl-2-chloropyridine (0.21 g, 1.5 mmol), 1-[3-(dimethylamino) propyl]-3-ethylcarbodiimide hydrochloric acid salt (0.29 g, 1.5 mmol) and chloroform (10 ml) was left at room temperature overnight. The mixture was extracted with chloroform, washed 1 N hydrochloric acid, a saturated sodium bicarbonate water and a saturated brine, dried on anhydrous sodium sulfate and then filtered. The residue obtained by concentrating the resulting filtrate was purified with a silica gel chromatography to obtain N-(6-chloro-3-pyridylmethyl)-3-ethoxy-2-(4-trifluoromethylphenyl hydrazono) propionic acid amide (Compound No. 170) (0.3 g, 0.72 mmol, 72%). Compound No. 170: mp 98-99C; 1H NMR (400 MHz, CDCl3) delta 1.20 (3H, t), 3.57 (2H, q), 4.36 (2H, s), 4.51 (2H, d), 6.22 (2H, d), 7.33 (1 H, d), 7.37 (1 H, d), 7.52 (2H, d), 7.52 (2H, d), 7.64 (1H, dd), 7.85 (1 H, brt).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,97004-04-1, (6-Chloropyridin-3-yl)methanamine, and friends who are interested can also refer to it.
