Related Products of 88095-61-8,Some common heterocyclic compound, 88095-61-8, name is 1-Benzyl-4-nitro-1H-pyrazole, molecular formula is C10H9N3O2, 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.

General procedure: To a 8 mL glass vial equipped with a magnetic stirbar were sequentially added K2CO3 (207 mg, 1.5 mmol), the nitroazole substrate (0.50 mmol), aryl halide (0.50 mmol oras indicated), toluene (0.50 M or 1.0 M), Pd(OAc)2 (5.60mg, 0.025 mmol) and [PCy3H]BF4 (18.4 mg, 0.050 mmol).The reaction mixture was purged with nitrogen through aTeflon-lined cap. Then the cap was replaced with a newTeflon-lined solid cap. The reaction vial was moved to a preheatedreaction block. After stirring for 18 h at the indicatedtemperature, the reaction mixture was cooled to 25 C and concentrated. The residue was purified by flash column chromatography to provide the desired arylated product.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Benzyl-4-nitro-1H-pyrazole, its application will become more common.
