With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14774-37-9,Tetrahydropyran-4-methanol,as a common compound, the synthetic route is as follows.
To a solution of tetrahydropyran-4-MeOH (5.0 g, 43 mmol) in CH2Cl2 (30 mL) was added Et3N (7.2 mL, 51.6 mmol). The mixture was cooled to 0 C., and methanesulfonyl chloride (4.0 mL, 51.6 mmol) was added. The mixture was stirred at 0 C. for several hours, then was slowly warmed to RT. The reaction was stirred at RT for 18 h, then was concentrated in vacuo. The residue was taken up in EtOAc and was washed with sat. NaHCO3. The organic layer was dried [MgSO4] and concentrated in vacuo to give the mesylate Part A(v)(a) compound (8.3 g, quantitative yield) as a white, needle-like solid.
14774-37-9, As the paragraph descriping shows that 14774-37-9 is playing an increasingly important role.
