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.
