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.
20 g of 2,2,6,6-tetramethylpiperidine are mixed with 40.7 g, 1.1 eq, of 15% sodium hydroxide solution and cooled to 5 to 10C. Over a period of 1.5 hours, 10.8 g, 1.1 eq. of chlorine gas are introduced, then nitrogen gas is used to drive out the excess chlorine and the mixture is warmed to room temperature (RT). After separating the phases, washing the aqueous phase with 25 ml of dichloromethane, drying the combined organic phases with magnesium sulphate and distilling off the dichloromethane in vacuo, 24.2 g, 99%), of l-chloro-2,2,6,6-tetramethylpiperidine are obtained., 768-66-1
768-66-1 2,2,6,6-Tetramethylpiperidine 13035, apiperidines compound, is more and more widely used in various fields.
