These common heterocyclic compound, 285984-25-0, name is 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine, 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. SDS of cas: 285984-25-0
b. Lambda/-(5-fert-Butyl-2-p-tolyl-2H-pyrazol-3-yl)-2-chloro-acetamide; A solution of 5-ferf-butyl-2-p-tolyl-2/-/-pyrazol-3-ylamine (886 mg, 3.86 mmol), pyridine (465 muL, 5.80 mmol) and chloroacetyl chloride (462 mul_, 5.80 mmol) in DCM (5 ml_) was stirred at RT for 2 h. The reaction mixture was diluted with aq. sat. sodium bicarbonate and DCM and the resulting aqueous layer was extracted twice with DCM. The combined organic layers were dried (MgSO4) and concentrated in vacuo to afford the title compound (1.17g, 100%) as a yellow solid. LCMS (Method 5): Rt 4.41 min, m/z 306 [MH+].
The synthetic route of 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine has been constantly updated, and we look forward to future research findings.
