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. 25699-98-3, name is 4′-(1-Pyrazolyl)acetophenone, A new synthetic method of this compound is introduced below., COA of Formula: C11H10N2O

1-(4-(1H-pyrazol-1-yl)phenyl)ethan-1-one (1.26 g, 6.8 mmol) and THF (25 mL) were stirred at ambient temperature in a 100 mL round flask. The mixture was cooled in an ice bath, and NaH (544 mg, 13.6 mmol, 2.0 eq.) was added slowly and stirred at ambient temperature for 5 minutes. CS 2 (620 muL, 10.2 mmol, 1.5 eq.) was added slowly and stirred at ambient temperature for 5 minutes. MeI (1.3 mL, 20.4 mmol, 3.0 eq.) was added slowly and stirred at 50 for 12 hours. After the reaction ended, H 2O was added for quenching, and the reactant was extracted with EtOAc. The organic solvent layer was dried over MgSO 4 and concentrated in vacuo. After that, Et 2O was added to the reactant and sonicated and filtered to provide the compound (1.3 g) (yield: 66%).

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.

General procedure: To a 15 mL dry Schlenk tube with a stirring bar, substrate 1 (0.3 mmol), 2 (0.36 mmol), and [Cp*Co(CO)I2] (5 mol%) were added under air. Then the tube was transferred into the glove box. AgSbF6 (10 mol%) was added. After moving out, DCE(2 mL) was injected into the tube under nitrogen. Then the tube was sealed and the mixture was stirred at 100 C for 12-48 hours. After cooling down, the solvents were removed under reduced pressure and the residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate) to give the desired coupling product.
