Reference of 1029413-53-3, A common heterocyclic compound, 1029413-53-3, name is tert-Butyl 3-(4-amino-1H-pyrazol-1-yl)pyrrolidine-1-carboxylate, molecular formula is C12H20N4O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Example 72C (1S,2S,3R,4R)-3-{[5-chloro-2-({1-[(3S)-pyrrolidin-3-yl]-1H-pyrazol-4-yl}amino)pyrimidin-4-yl]amino}bicyclo[2.2.1]hept-5-ene-2-carboxamide (+)-(1S,2S,3R,4R)-3-(2,5-Dichloropyrimidin-4-ylamino)bicyclo[2.2.1]hept-5-ene-2-carboxamide (75 mg, 0.25 mmol) and (S)-tert-butyl 3-(4-amino-1H-pyrazol-1-yl)pyrrolidine-1-carboxylate (63 mg, 0.25 mmol) were combined with 2-propanol (2.4 ml) in a sealed tube and the mixture was heated to 85 C. for 4 hours. The reaction mixture was concentrated to dryness, then treated with 5 mL TFA and stirred for 15 minutes. The mixture was again concentrated to dryness, the residue was dissolved in CH2Cl2, and the mixture was treated with aqueous saturated NaHCO3. The layers were separated and the aqueous layer was further extracted 3* with ethyl acetate. The extracts were dried (Na2SO4) and concentrated, then purified by flash chromatography yielding the desired product. 1H NMR (300 MHz, DMSO-D6) ppm 1.41 (d, J=7.8 Hz, 1H) 1.92-2.04 (m, 1H) 2.07-2.21 (m, 2H) 2.52-2.56 (m, 1H) 2.71-2.91 (m, 3H) 2.93 (d, J=5.4 Hz, 1H) 2.95-3.03 (m, 1H) 3.12 (dd, J=11.5, 7.12 Hz, 1H) 4.13 (t, J=7.5 Hz, 1H) 4.65-4.77 (m, 1H) 6.25-6.40 (m, 2H) 7.25 (s, 1H) 7.51 (s, 1H) 7.61-7.84 (m, 3H) 7.89 (s, 1H) 9.10 (s, 1H); MS (ESI(+)) m/e 415 (M+H)+.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
