Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 3994-50-1, name is 1-Methyl-4-nitro-1H-pyrazole, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 1-Methyl-4-nitro-1H-pyrazole
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.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 3994-50-1.
