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. 16063-69-7, name is 2,4,6-Trichloropyridine, the common compound, a new synthetic route is introduced below. name: 2,4,6-Trichloropyridine
A mixture of 2,4,6-trichloropyridine (2.22 g, 12.20 mmol), methyl trans-4-aminocyclohexanecarboxylate hydrochloride (2.6 g, 13.42 mmol) and cesium carbonate (6.74 g, 48.8 mmol) in DMF (30 mL) was stirred in a sealed tube at 150 C. After 5.5 hours, the crude was poured on water (30 mL) and EtOAc (30 mL). The aqueous phase was extracted with EtOAc (3×20 mL). The combined organic phases were dried (Na2SO4), filtered and concentrated. Purification of the residue by flash chromatography (hexanes/ethyl acetate 15% to 30% ethyl acetate) gave the title compound (1.02 g, 28%) as a yellow solid.LRMS (m/z): 303/305 (M+1)+.1 H NMR (250 MHz, CHLOROFORM-d) delta ppm 1.24 (m, 4H), 1.6 (m, 2H), 2.11 (m, 2H), 2.31 (m, 1 H), 3.26 (m, 1 H), 3.69 (s, 3H), 4.32 (d, J = 7.3 Hz, 1 H), 6.34 (s, 2H)
The synthetic route of 16063-69-7 has been constantly updated, and we look forward to future research findings.
