5773-58-0, 3-Methylpiperidin-4-one is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
5773-58-0, 13.3: tert-butyl 3-methyl-4-oxopiperidine-1-carboxylate; 6.8 g of 3-methylpiperidin-4-one, 16.7 ml of triethylamine, 19.6 g of di-t-butyl dicarbonate and 0.7 g of dimethylaminopyridine are placed in a mixture of 300 ml of THF and 30 ml of water. Stirring is maintained at ambient temperature for 18 h. After evaporation of the THF, the reaction medium is treated with a saturated aqueous potassium hydrogen sulphate solution to a pH of 1, and then extraction is carried out with ethyl acetate until the aqueous phase is completely depleted. The organic phase is then washed with a saturated aqueous potassium hydrogen sulphate solution, and then with a saturated aqueous sodium hydrogen carbonate solution and, finally, with a saturated aqueous sodium chloride solution. After drying over MgSO4 and concentration to dryness, the crude obtained is chromatographed on silica gel, elution being carried out with a 98/2 dichloromethane/methanol mixture. 10.3 g of tert-butyl 3-methyl-4-oxopiperidine-1-carboxylate are obtained.
As the paragraph descriping shows that 5773-58-0 is playing an increasingly important role.
