With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.768-66-1,2,2,6,6-Tetramethylpiperidine,as a common compound, the synthetic route is as follows.,768-66-1
A dry and nitrogen-flushed Schlenk flask equipped with a magnetic stirring bar and rubber septum was charged with iPrMgCl·LiCl (1.0 M in THF, 20 mL 20 mmol). Then, 2,2,6,6-tetramethylpiperidine (3.52 mL, 21 mmol) was added dropwise through a syringe within 5 min. The mixture was stirred until the gas evolution ceased (24-48 h). Titration against benzoic acid in THF (0 C) in the presence of 4-(phenylazo)diphenylamine as the indicator showed that the base concentration ranged from 0.9 to 0.98 M.
The synthetic route of 768-66-1 has been constantly updated, and we look forward to future research findings.
