Downstream synthetic route of 2081-44-9

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.

To a solution of tetrahydro-2H-pyran-4-ol (500 mg, 4.90 mmol) in DCM (16 mL) was added TEA (0.882 mL, 6.36 mmol) followed by MsCl (0.458 mL, 5.87 mmol) at 0 C. The reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was diluted with DCM, washed with water, 2 N aq. HCl, saturated aq. NaHCO3, and brine successively, dried over Na2SO4, filtered and concentrated in vacuo to afford tetrahydro-2H-pyran-4-yl methanesulfonate (882 mg, 100%) as a colorless oil, which was used for the next reaction without further purification. 1H-NMR (CDCl3, Varian, 400 MHz): delta 1.84-1.92 (2H, m), 2.03-2.07 (2H, m), 3.04 (3H, s), 3.52-3.58 (2H, m), 3.92-3.97 (2H, m), 4.87-4.93 (1H, m).
