Downstream synthetic route of 2081-44-9

The synthetic route of 2081-44-9 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2081-44-9,Tetrahydro-2H-pyran-4-ol,as a common compound, the synthetic route is as follows.

Preparation Example 50 To a solution of tetrahydro-2H-pyran-4-ol (1.00 g) in pyridine (10 mL) was added 4-methylbenzenesulfonyl chloride under ice-cooling, and the reaction mixture was stirred at room temperature for 3 days. To the reaction mixture was added water, followed by extraction with ethyl acetate. The organic layer was washed with 1 M hydrochloric acid, a saturated aqueous sodium hydrogen carbonate solution, and a saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The desiccant was removed by filtration and the solvent was evaporated under reduced pressure to obtain tetrahydro-2H-pyran-4-yl 4-methylbenzenesulfonate (2.72 g) as a pale orange oil., 2081-44-9

The synthetic route of 2081-44-9 has been constantly updated, and we look forward to future research findings.
