Application of 400877-57-8,Some common heterocyclic compound, 400877-57-8, name is Methyl 1-methyl-4-nitro-1H-pyrazole-3-carboxylate, molecular formula is C6H7N3O4, 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.
A solution of methyl 1-methyl-4-nitro-1H-pyrazole-3-carboxylate (1.0 g, 5.41 mmol) and Pd/C (200 mg) in MeOH (60 mL) was stirred for 1 hour at 25C. Pd/C was filtered out and the filtrate was concentrated to give desired compound as a white solid (800 mg, 95%).
The synthetic route of 400877-57-8 has been constantly updated, and we look forward to future research findings.
