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
To a 1 liter four-necked round bottom flask equipped with a mechanical stirrer, a reflux condenser, a thermometer, a funnel and a septum are added 80 g of water, 20 g K2CO3 (99%; 0,1448 mol), 10 g 2,2,6,6-tetramethylpiperidine (99%; 7,079·10-2 mol) and 100 g toluene. Then, a solution of 15,34 g of peracetic acid (7,06·10-2 mol) in 80 g water is added slowly to the 1 liter flask while stirring vigorously (with a slightly exothermic reaction) and the flask is placed in a water bath at room temperature. After the addition is complete, the reaction medium is stirred at room temperature overnight and the organic phase becomes red due to the formation of 2,2,6,6-tetramethylpiperidine-1-oxide (TEMPO).
As the paragraph descriping shows that 768-66-1 is playing an increasingly important role.
