344329-76-6, Tetrahydro-2H-pyran-4-carboxamide is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
d) Tetrahydropyran-4-carbonitrile can be prepared as follows: Slowly add 10 cm3 of thionyl chloride to 3 g of tetrahydropyran-4-carboxamide cooled on an ice bath. Heat the mixture at 80 C. for two hours, then concentrate under vacuum. Take up the residue in 20 cm3 of water and adjust the pH of the solution to pH 7 with potassium hydroxide. Extract the aqueous phase with ethyl acetate (4*50 cm3). The combined organic phases are washed with water (2*50 cm3), dried over magnesium sulphate, and then concentrated under vacuum to obtain 2.47 g of tetrahydropyran-4-carbonitrile., 344329-76-6
As the paragraph descriping shows that 344329-76-6 is playing an increasingly important role.
