695-53-4,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.695-53-4,5,5-Dimethyloxazolidine-2,4-dione,as a common compound, the synthetic route is as follows.
A mixture of 1,2-dicyanonaphthalene (0.071 g, 0.4 mmol), 2 (0.103 g, 0.8 mmol), anhydrous NiCl2 (0.104 g, 0.8 mmol), urea (0.096 g, 1.6 mmol) and a catalytic amount of MOA was stirred in quinoline (5 mL) at 250 C under argon for 30 min. After cooling to room temperature, the reaction mixture was diluted with 50% ethanol (50 mL). The resultant precipitate was filtered off and washed successively with hot water and hot 50% ethanol until the washings were colorless. The crude residue was extracted with toluene using a Soxhlet apparatus, which was concentrated to approximately 5 mL, and purified by silica gel column with toluene as the eluent. The green-blue fraction was collected to give 7.5 mg of 5 (8.0%). MASS (MALDI) (m/z): 702 (M+).
695-53-4 5,5-Dimethyloxazolidine-2,4-dione 3081, aoxazolidine compound, is more and more widely used in various fields.
