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.

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.
