Adding a certain compound to certain chemical reactions, such as: 35344-95-7, name is 1H-Pyrazole-4-carbaldehyde, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 35344-95-7, SDS of cas: 35344-95-7
To a stirred solution of lH-pyrazole-4-carbaldehyde (S2-1) (200 mg, 2.08 mmol) in DMF (2 rnL) was added 2-iodopropane (707.66 mg, 4.16 mmol, 416.27 uL) and Cesium carbonate (1.36 g, 4.16 mmol) at ambient temperature. The resulting mixture was heated at 80C for 16 hours. It was then cooled to room temperature, diluted with ice cold w’ater and extracted with ethyl acetate. The combined extract was washed with brine, dried over sodium sulfate, and concentrated under reduced pressure. The reaction mixture was purified by flash chromatography (eluting with 30% ethyl acetate-hexane) to afford l-isopropylpyrazoJe-4-carbaldehyde (S2-2) (200 mg, 1.45 mmol, 69.54% yield) as brown liquid. LCMS: ES+ 139.1.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1H-Pyrazole-4-carbaldehyde, other downstream synthetic routes, hurry up and to see.
