In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 14752-66-0, name is Sodium 4-chlorobenzenesulfinate belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Quality Control of Sodium 4-chlorobenzenesulfinate
Example 74: 4-[1-[(4-Chlorophenyl)sulfonyl]-5-(methylsulfonyl)pentyl]pyridine sodium 4-chlorobenzenesulfinate (207 mg, 1.04 mmol), 3-chloromethylpyridine hydrochloride (171 mg, 1.04 mmol) and potassium acetate (204 mg, 2.08 mmol) were added to n-butanol (5 ml).. The resulting mixture was stirred at 70C for 5 hours.. After cooling to room temperature, the solvent was concentrated under reduced pressure.. To the residue was added ethyl acetate and from the resulting mixture, the insoluble matter was filtered off.. The filtrate was concentrated under reduced pressure.. The residue was subjected to chromatography on a silica gel column and the from the fraction eluted with hexane:ethyl acetate (=2:3), a white solid (117 mg) was obtained. Then, a toluene (10 ml) solution of the resulting solid (52 mg), the 4-(methylsulfonyl)-1-butanol (90 mg, 0.592 mmol) obtained in Referential Example 3 and cyanomethylenetri-n-butylphosphorane (140 mg, 0.582 mmol) was heated under reflux for 2 days under an argon atmosphere..
The synthetic route of 14752-66-0 has been constantly updated, and we look forward to future research findings.
