With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.18494-87-6,Benzothiophene-3-sulfonyl chloride,as a common compound, the synthetic route is as follows.

Example 393; 7-[1-(1-benzothien-3-ylsulfonyl)piperidin-4-yl]-3,3-dimethyl-2-oxa-7-azaspiro[4.5]decan-1-one; [Show Image] To a solution of 3,3-dimethyl-7-(piperidin-4-yl)-2-oxa-7-azaspiro[4.5]decan-1-one dihydrochloride (150 mg, 0.442 mmol) obtained in Reference Example 53 and triethylamine (0.215 mL, 1.55 mmol) in THF (2 mL) was added 1-benzothiophene-3-sulfonyl chloride (103 mg, 0.442 mmol), and the mixture was stirred at room temperature for 3 hr. The reaction mixture was diluted with ethyl acetate, washed with aqueous potassium carbonate solution and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was purified by basic silica gel column chromatography (developing solvent; ethyl acetate) to give the title compound (180 mg, yield 88%). EI(pos) 463 [M+H]+, 18494-87-6

18494-87-6 Benzothiophene-3-sulfonyl chloride 2776340, abenzothiophene compound, is more and more widely used in various fields.
