With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1214196-85-6,1-(tert-Butoxycarbonyl)piperazine-2-carboxylic acid,as a common compound, the synthetic route is as follows.
A mixture of 1-(tert-butoxycarbonyl)piperazine-2-carboxylic acid (23 g, 100 mmol) in THF (200 mL) was added NaOH (1 mol/L in H2O, 200 mL, 200 mmol), followed by added Cbz-Cl (19 g, 110 mmol) dropwise. The mixture was stirred at 25 C. for 4 hours. HCl (1N in H2O) was added to pH=5, the organic phase was washed with H2O, brine, dried and evaporated to afford product as yellow oil (25 g, 69%). MS (ESI): mass calcd. for C18H24N2O6 364.16, m/z found 365.1 [M+H]+., 1214196-85-6
The synthetic route of 1214196-85-6 has been constantly updated, and we look forward to future research findings.
