Synthetic Route of 288-36-8, The chemical industry reduces the impact on the environment during synthesis 288-36-8, name is 1H-1,2,3-Triazole, I believe this compound will play a more active role in future production and life.
iV-Bromosuccinimine (456 mg, 2.56 mmol) and benzoylperoxide (61 mg, 0.25 mmol) was added to a warm (-77 0C) suspension of methyl 6-methoxy-3-[(4-methyl-l- 5 naphthoyl)amino]pyrazine-2-carboxylate, prepared in Example 25F or alternatively in Example 44E3 (883 mg, 2.51 mmol) in CCl4 (60 ml). The resulting reaction mixture was heated at reflux for 2.5 h. Additional amount of benzoylperoxide (catalytic, tip of a spatula) was added and reaction mixture was heated at reflux for a further 12 h. After removal of solvents, the residue was dissolved in EtOAc, washed with water and saturated 0 aqueous NaCl, dried (Na2SO4), and evaporated to give crude benzyl bromide (1.14 g). To this crude benzyl bromide (1.13 g) dissolved in acetonitrile (50 ml) at reflux was added 1,2,3-triazole (0.487 ml, 8.40 mmol) and the resulting mixture was heated at reflux over night (16 h). The solution was then evaporated under reduced pressure, and the residue was purified by revered-phase HPLC (30-?100% MeCN in 0.1M aqueous NH4OAc; followed 5 by 30-?100% MeCN in 0.15% aqueous TFA) to give methyl 6-methoxy-3 -{[4-( IH- 1,2,3 – triazol-l-ylmethyl)-l-naphthoyl]amino}pyrazine-2-carboxylate as the corresponding TFA
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1H-1,2,3-Triazole, other downstream synthetic routes, hurry up and to see.
