With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1158759-06-8,tert-Butyl 3-amino-3-methylpiperidine-1-carboxylate,as a common compound, the synthetic route is as follows.
Step 5. tert-Butyl 3-methyl-3-((7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)piperidine-1-carboxylate. tert-Butyl 3-amino-3-methylpiperidine-1-carboxylate (3.3 g, 15.398 mmol) and tert-butyl 3-amino-3-methylpiperidine-1-carboxylate (3.9 g, 12.7 mmol) was stirred at 140 C. overnight. After TLC showed tert-butyl 3-amino-3-methylpiperidine-1-carboxylate to be consumed, the mixture was diluted with DCM (80 ml). The DCM layer was washed with sat NaHCO3 (aq) and brine and concentrated to dryness to give crude product which was purified by chromatography (silica, EtOAc/Petroleum ether, 0-40%) to give tert-butyl 3-methyl-3-((7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)piperidine-1-carboxylate (2.4 g, 40%) as a white solid
1158759-06-8, 1158759-06-8 tert-Butyl 3-amino-3-methylpiperidine-1-carboxylate 20816952, apiperidines compound, is more and more widely used in various fields.
