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. 486460-21-3, name is 3-(Trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine belongs to Pyrazines compound, it is a common compound, a new synthetic route is introduced below. 486460-21-3
333 mg (1 mmol) of 3S-t-butoxycarbonylamino-4-(t-butyl-dimethyl-silanyloxy)- butanoic acid which was obtained from step (1) was added 192 mg (1 mmol) of 3-trifluoromethyl-5,6-dihydro-8H-[l,2,4]triazolo[4,3-a]pyrazine, and the resulting mixture was dissolved in dichloromethane. The reaction solution was cooled to 0C, and 162 mg (1.2 mmol) of HOBT was added, followed by stirring for 10 minutes and then addition of 288 mg (1.5 mmol) of EDC. After removal of an icebath, the reaction solution was stirred for abour 13 hours, and then the residue, which was obtained by concentration was purified by column chromatography (1:1 hexane: ethyl acetate) to give 0.27 g of the title compound in yield of 53%.[582] 1H NMR (CDCl3) delta 5.1-5.3 (IH, m), 4.9-5.1(2H, m), 3.9-4.3 (4H, m), 3.7-3.8 (2H, m), 2.6-2.9 (2H, m), 1.40(9H, s), 0.87 (9H, s), 0.03 (6H, s)[583] Mass (m/e) 508 (M+l)
The synthetic route of 486460-21-3 has been constantly updated, and we look forward to future research findings.
