Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 31108-57-3, name is 1H-Pyrazole-4-carbonitrile, A new synthetic method of this compound is introduced below., Application In Synthesis of 1H-Pyrazole-4-carbonitrile
A solution of compound from Example 115 step b (100 mg, 0.19 mmol), 1H- pyrazole-4-carbonitrile (43 mg, 0.46 mmol), CuI (53 mg, 0.28 mmol), K2CO3 (102 mg, 0.74 mmol), (1S,2S)-1-N,2-N-dimethylcyclohexane-1,2-diamine (52.8 mg, 0.37 mmol) in DMF(3 mL) was stirred for 2 hrs at 100oC under N2. The crude product was purified by HPLC to give the desired compound (66 mg, 65%) as a white solid. ESI MS m/z = 549.2 [M+H]+.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
