Analyzing the synthesis route of 24340-77-0

With the synthetic route has been constantly updated, we look forward to future research findings about 4-Bromoisothiazole,belong isothiazole compound

As a common heterocyclic compound, it belong isothiazole compound,4-Bromoisothiazole,24340-77-0,Molecular formula: C3H2BrNS,mainly used in chemical industry, its synthesis route is as follows.,24340-77-0

The above oily liquid was dissolved in 10 mL of ethylene glycol dimethyl ether and 2 mL of water, and 4-bromoisothiazole (163 mg, 0.99 mmol), Pd(PPh3)4 (29 mg, 0.025 mmol) and Na2CO3 (263 mg, 2.48 mmol), the reaction was stirred at 100 C for 2 hours under nitrogen atmosphere. After cooling to room temperature, the reaction solution was poured into 60 mL of water and extracted three times with 20 mL of ethyl acetate. The combined ethyl acetate was washed with brine and dried over anhydrous sodium sulfate. Filtered, and concentrated by column chromatography (petroleum ether / ethyl acetate 1/1) to give 43mg as a white solid powder.

With the synthetic route has been constantly updated, we look forward to future research findings about 4-Bromoisothiazole,belong isothiazole compound
