Reference of 82560-12-1<\/a>, A common heterocyclic compound, 82560-12-1, name is 3-Amino-5-tert-butylpyrazole, molecular formula is C7H13N3, 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.<\/p>\n

A microwave vial was charged with 3-tert butyl- lH-pyrazole-5 -amine (1.03 g, 7.39 mmol), copper (I) iodide (70.3 mg, 0.37 mmol) and potassium carbonate (2.14 g, 15.5 mmol) and the vial sealed with a septum, evacuated and purged with argon. Trans- N,N’-dimethylcyclohexane-l,2-diamine (210 mg, 1.48 mmol) was then added, then a solution of Intermediate Vc (4.26 g, 8.86 mmol) in toluene (7.5 mL, degassed with argon) was added, and the reaction was subjected to microwave irradiation (150 C for 1 h). The reaction mixture was then filtered through Celite, and the filtrate concentrated in vacuo. Purification by FCC, eluting with 0 – 60% EtOAc\/cyclohexane, to afford the title compound (2.41 g, 66%). LCMS (Method 3) Rt 4.68 min, m\/z 493, 495 [MH+].<\/p>\n

The synthetic route of 82560-12-1 has been constantly updated, and we look forward to future research findings.<\/p>\n
