Synthetic Route of 5932-27-4, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 5932-27-4 as follows.

General procedure: Pyrazoles 4 (0.5 mmol), sodium sulfinate 2 (1.0 mmol) and NBS or NIS (1.5 mmol) were dissolved in 2 mL of EtOAc solvent. the reaction mixture was stirred at room temperature under air for 12 h. After the reaction, the resulting mixture was extracted with EtOAc. The combined organic phase was dried over anhydrous Na2SO4 and the solvent was then removed under vacuum. The residue was purified by flash column chromatography on silica gel (petroleum ether/ethyl acetate, 3:1) to afford the corresponding product.
