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.
EXAMPLE 14 1-[2,4-DICHLORO-5-(TETRAHYDRO-4H-PYRAN-4-YLOXY)PHENYL]-3-METHYL-4-DIFLUOROMETHYL-Delta2 -1,2,4-TRIAZOLIN-5-ONE To a chilled solution of 1.0 g (0.0098 mole) of tetrahydro-4H-pyran-4-ol in 10 mL of pyridine was added 1.91 g (0.01 mole) of 4-methylphenylsulfonyl chloride over 3-5 minutes. The reaction mixture was stirred at about -4 C. for 15 minutes, then was allowed to stand with cooling for 16 hours. The reaction mixture was mixed with ice-water, and the solid product, tetrahydro-4H-pyran-4-yl 4-methylphenylsulfonate, collected on a filter paper, wgt. 1.6 g, mp 56-57 C., 2081-44-9
The synthetic route of 2081-44-9 has been constantly updated, and we look forward to future research findings.
