36% | With sodium hydroxide; In tetrahydrofuran; water; at 20℃; | Step 4. tert-Butyl 3-amino-3-methylpiperidine-1-carboxylate. To a solution of tert-butyl 3-isocyanato-3-methylpiperidine-1-carboxylate (5.89 g, 24.54 mmol) in THF (140 ml) was added 2M NaOH (aq) (140 ml). The resulting solution was stirred vigorously at room temperature overnight. TLC showed the desired product was formed. The reaction mixture was acidified to pH 1 with 1M HCl (aq) and then extracted with MTBE (200 ml×3). The organic layers were discarded. The resulting aqueous layer was basified to pH 10 with 1M NaOH (aq.) and then extracted with MTBE (250 ml×3). The combined organic layers were washed with brine to neutral pH, dried over Na2SO4 and concentrated to dryness to give tert-butyl 3-amino-3-methylpiperidine-1-carboxylate (3.7 g, 36%) as colorless oil which was directly used to the next step without further purification. 1H NMR (400 MHz, CHCl3) delta d 1.09 (s, 3H) 1.27-1.40 (m, 2H) 1.46 (s, 10H) 1.53-1.65 (m, 2H) 3.04-3.56 (m, 4H). |
With sodium hydroxide; In tetrahydrofuran; at 20℃; for 20.0h; | To a solution of 812 mg (3.38 mmol) rac-3-isocyanato-3-methyl-piperidine-1-carboxylic acid tert-butyl ester in 17 ml THF were added 16.9 ml 2N NaOH and the emulsion stirred vigorously at ambient temperature for 20 h. The emulsion was diluted with tert-butyl methyl ether and extracted three times. The combined extracts were washed with brine to neutral pH, dried over sodium sulfate, filtered and evaporated. The crude product was purified by column chromatography on silica gel with a gradient of heptane and 10 to 100% ethyl acetate then with ethyl acetate/MeOH provided the title compound: 232 mg colourless oil which crystallized at ambient temperature MS (m/e): 215.2 (M+H). |

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) <strong>[1158759-06-8]rac-3-amino-3-methyl-piperidine-1-carboxylic acid tert-butyl ester</strong> 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). |

40% | at 140℃; | 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 <strong>[1158759-06-8]tert-butyl 3-amino-3-methylpiperidine-1-carboxylate</strong> (3.9 g, 12.7 mmol) was stirred at 140 C. overnight. After TLC showed <strong>[1158759-06-8]tert-butyl 3-amino-3-methylpiperidine-1-carboxylate</strong> 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 |

17% | With trifluoroacetic acid; In isopropyl alcohol; at 90℃; for 16.0h; | 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. |

80% | With triethylamine; In dichloromethane; | 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). |
