Synthetic Route of 16681-70-2, 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. 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below.
[003 87] To a solution of (+/-)-cis-N1 -(2-chloro-7-methyl-7H-pyrrolo[2, 3 -d]pyrimidin-4-yl) cyclohexane-1,3-diamine (60 mg, 0.21 mmol) in a mixed solvent of tetrahydrofuran (4 mL) and dimethyl sulfoxide (1 mL) was added N,N-diisopropylethylamine (0.11 mL, 0.64 mmol) and 1H-1,2,3-triazole-4-carboxylic acid (48 mg, 0.43 mmol). The mixture was stirred at rt for 10 minitues, and then HATU (163 mg, 0.43 mmol) was added. The resulting mixture was stirred at rt for 3 h. To the reaction mixture was added water (10 mL), and the resulting mixture was extracted with ethyl acetate (10 mL x 3). The combined organic layers were washed with saturated brine (30 mL), dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated in vacuo to dry and give the title compound as a colorless solid (83 mg, 100%).MS (ESI, pos.ion) m/z: 375.2 [M+H]+
The synthetic route of 1H-[1,2,3]Triazole-4-carboxylic acid has been constantly updated, and we look forward to future research findings.
