Downstream synthetic route of 695-53-4

As the paragraph descriping shows that 695-53-4 is playing an increasingly important role.

695-53-4, 5,5-Dimethyloxazolidine-2,4-dione is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

695-53-4, To 20.1 g of Exemplified compound (5) in 200 ml of methylene chloride solution, 4.8 g of bromine in 50 ml of methylene chloride solution was added dropwise, while the mixture was cooled on ice. After stirring was continued at room temperature for 30 minutes, water was added to the resulting mixture. The aqueous phase was separated. The organic phase was dried with magnesium sulfate anhydride, and then condensed by vacuum distillation. 50 ml of N,N-dimethylacetoamide was added to the residue. The resulting mixture was added dropwise to 12.7 g of 5,5-dimethyloxazolidine-2,4-dione and 12.5 ml of triethylamine in 200 ml of N,N-dimethylacetoamide solution, while the mixture was cooled on ice. After stirring was continued at room temperature for 2 hours, the mixture was stirred at 40 C. for further 1 hour. Ethyl acetate and 400 ml of aqueous solution of sodium hydroxide (20 g) were added. The aqueous phase was separated. The organic phase was washed with 150 ml of 1N-hydrochloric acid and 150 ml of water, and dried with magnesium sulfate anhydride, and then condensed by vacuum distillation. The residue was crystallized from a mixed solvent of ethyl acetate and hexane to obtain 16.7 g of Exemplified compound (3).
