406212-51-9, 1-tert-Butyl 3-methyl 4-hydroxypiperidine-1,3-dicarboxylate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of methyl 4-hydroxypiperidine-3-carboxylate (3.18 g, 20 mmol), aqueous sodium hydrogen carbonate (30 mL, 1M), di-tert-butyl dicarbonate (4.37 g, 20 mmol) and dichloromethane (30 mL) was stirred for 15 hours. The phases were separated and dichloromethane phase was dried over anhydrous sodium sulfate and filtrated. The filtrate was diluted to 200 mL. To the resulted solution was added imidazole (1.64 g, 24 mmol), DMAP (0.488 g, 4 mmol), and TBDMSCl (3.62 g, 24 mmol) sequentially. The reaction mixture was stirred at room temperature for 40 hours. The mixture was washed with 1N HCl solution, NaHCO3 solution and brine sequentially and dried over anhydrous sodium sulfate. Filtration and concentration gave the crude compound which was used directly in the next step. MS (m/z): 274 (M-Boc+H)+., 406212-51-9
The synthetic route of 406212-51-9 has been constantly updated, and we look forward to future research findings.
