Reference of 64517-88-0, A common heterocyclic compound, 64517-88-0, name is 1,3-Dimethyl-1H-pyrazol-4-amine, molecular formula is C5H9N3, 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.
[5]; 2-(6-Chlorobenzotriazol-l-yl)-l,l,3,3-tetramethyluronium tetrafluoroborate was used in place of 2-(7-azabenzotriazol- 1 -yl)- 1 , 1 ,3,3-tetramethyluronium hexafluorophosphate(V) as the coupling agent. The product gave the following characterising data :- 1H NMR Spectrum: (DMSOd6) 2.13 (s, 3H), 3.66 (s, 2H), 3.70 (s, 3H), 3.78 (s, 3H), 6.77 (d, IH), 6.91 (m, IH), 7.06 (d, IH), 7.37 (d, IH), 7.81 (s, IH)5 8.08 (s, IH), 8.92 (s, IH), 9.44 (s, IH), 9.57 (d, IH); Mass Spectrum: M+H+ 438 and 440.
The synthetic route of 64517-88-0 has been constantly updated, and we look forward to future research findings.
