53911-68-5, 4-(4-Chlorophenyl)dihydro-2H-pyran-2,6(3H)-dione is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
53911-68-5, A solution of triethyl amine (1.5 ml) in 1,4-dioxane (5 ml) was added to a mixture of commercial 4- phenoxyaniline (1.85 g) and 3-(4-chlorophenyl)glutaric anhydride. The resulting solution was stirred at rt for 0.5 h and at 400C for 2 h. Under cooling with ice cone. HCI (2 ml) and water (10 ml) was added. A gummy precipitate is formed from which the aqueous layer is removed by decantation. Crystallisation was induced by heating with methanol (5 ml). After cooling in the refrigerator the precipitate was isolated by filtration, washed with methanol and diethyl ether, and dried in vacuo to give colourless, powdery crystals (3 g) of /V-(4-phenoxyphenyl)-3-(4-chlorophenyl)- glutaramic acid.
53911-68-5 4-(4-Chlorophenyl)dihydro-2H-pyran-2,6(3H)-dione 104639, aTetrahydropyrans compound, is more and more widely used in various fields.
