171504-98-6,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.171504-98-6,Methyl 1,4-Bis(Boc)-2-piperazinecarboxylate,as a common compound, the synthetic route is as follows.
Methyl 1,4-di-tert-butoxycarbonylpiperazine-2-(R)-carboxylate (2.9 g, 8.5 mmol) was dissolved in 4M HCl in dioxane (30 ml) and stirred at room temperature for 30-60 minutes, forming a thick white precipitate. The reaction mixture was concentrated in vacuo and the resulting white solid dried under high vacuum to give methyl piperazine-2-(R)-carboxylate dihydrochloride (1.9 g, 100%). LC/MS Calcd for [M+H]+ 145.1. found 145.1.
The synthetic route of 171504-98-6 has been constantly updated, and we look forward to future research findings.
