Related Products of 2469-99-0, These common heterocyclic compound, 2469-99-0, name is 3-Oxobutanenitrile, 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.
Step B: 5-Methyl-2-phenyl-2H-pyrazol-3-ylamine Into a 1000-mL 3-necked round bottom flask, was placed a solution of 3-oxobutanenitrile (23 g, 277.11 mmol, 1.00 equiv) in ethanol (400 mL), 1-phenylhydrazine (30 g, 277.78 mmol, 1.00 equiv). The resulting solution was heated to reflux overnight in an oil bath. The resulting mixture was then concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:10-1:5) to yield 3-methyl-1-phenyl-1H-pyrazol-5-amine as a yellow solid.
The synthetic route of 2469-99-0 has been constantly updated, and we look forward to future research findings.
