Reference of 29683-23-6, Adding some certain compound to certain chemical reactions, such as: 29683-23-6, name is Tetrahydro-2H-thiopyran-4-ol,molecular formula is C5H10OS, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 29683-23-6.
Step 1 Tetrahydro-2H-thiopyran-4-yl-4-methylbenzenesulfonate Tetrahydro-2H-thiopyran-4-ol 23a (350 mg, 2.97 mmol, prepared by a method disclosed in EP patent application ”) was placed in a reaction flask, followed by addition of triethylamine (606 mg, 5.94 mmol), 4-dimethylaminopyridine (36 mg, 0.30 mmol), 20 mL of dichloromethane and p-toluenesulfonyl chloride (848 mg, 4.45 mmol). After reacting for 12 hours, the reaction solution was mixed with 30 mL of water, stood and layered, the aqueous phase was extracted with dichloromethane (10 mL*2). The organic phases were combined, washed with saturated sodium chloride solution (30 mL), dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography with elution system B to obtain the title compound tetrahydro-2H-thiopyran-4-yl-4-methylbenzenesulfonate 23b (556 mg, yield 68.9%) as a white solid.
