1158759-06-8, tert-Butyl 3-amino-3-methylpiperidine-1-carboxylate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To 3.15 ml 1M lithium aluminium hydride in THF was added at 5-10 C. drop-wise a solution of 225 mg (1.05 mmol) rac-3-amino-3-methyl-piperidine-1-carboxylic acid tert-butyl ester in 4 ml dry THF. The reaction mixture was heated to 65 C. for 1 h. The turbid reaction solution was cooled with an ice bath and below 12 C., were added drop-wise 0.13 ml water, 0.32 ml 2N NaOH and further 0.19 ml water. The suspension was diluted with tert-butyl methyl ether, dried over sodium sulfate, filtered and acidified with 2N HCl in diethyl ether. Evaporation provided 210 mg of the title compound as a colourless semisolid. MS (m/e): 129.3 (M+H)., 1158759-06-8

The synthetic route of 1158759-06-8 has been constantly updated, and we look forward to future research findings.

1158759-06-8, tert-Butyl 3-amino-3-methylpiperidine-1-carboxylate is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Into a 50-mL round-bottom flask, was placed 2-chloro-N-methylpyrimidin-4- amine (200 mg, 1.39 mmol, 1 equiv), tert-butyl 3-amino-3-methylpiperidine-l -carboxylate (357 mg, 1.67 mmol, 1.20 equiv), trifluoroacetic acid (791 mg, 7.00 mmol, 5.02 equiv), IPA (4 mL). The resulting solution was stirred for 16 h at 90 C in an oil bath. The crude product was purified by Prep-HPLC C NH4HCO3. This resulted in 52.4 mg (17%) N4-methyl-N2-(3- methylpiperidin-3-yl)pyrimidine-2,4-diamine as a light yellow solid., 1158759-06-8

As the paragraph descriping shows that 1158759-06-8 is playing an increasingly important role.

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.

A solution of tert-butyl 3-amino-3-methylpiperidine-l-carboxylate (0.1091 g, 0.5091 mmol) and TEA (0.1419 mL, 1.018 mmol) in DCM (5.1 mL) was treated with acetic anhydride (72.05 mu, 0.7636 mmol). The reaction was monitored for completion by TLC (EtOAc/ silica, using ninhydrin stain). Upon completion, the reaction mixture was diluted with DCM (40 mL) and washed with brine (3 x 20 mL). The organic extracts were dried over anhydrous MgS04(S), filtered, and concentrated in vacuo. The crude residue was purified by silica chromatography using DCM as eluent to afford title compound (0.104 g, 80% yield). MS (apci) m/z = 157.2 (M+H-Boc).

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.
