With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4295-99-2,4-Cyanotetrahydro-4H-pyran,as a common compound, the synthetic route is as follows.,4295-99-2
c) Methyl tetrahydro-2H-pyran-4-carboximidoate can be prepared as in Example 13, but from 3 g of tetrahydropyran-4-carbonitrile, 1.2 cm3 of methanol and 6 cm3 of ether. 4.4 g of methyl tetrahydro-2H-pyran-4-carboximidoate hydrochloride is obtained in the form of a white solid.
As the paragraph descriping shows that 4295-99-2 is playing an increasingly important role.
