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
(a) A mixture of 1 (0.10 g, 0.77 mmol), 2 (0.10 g, 0.77 mmol), anhydrous NiCl2 (0.1 g, 0.8 mmol), urea (0.09 g, 1.55 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 resulting precipitate was filtered, and washed successively with hot water and hot 50% ethanol until the washings were colorless. The crude residue was transferred to a Soxhlet apparatus, and was extracted with toluene. The toluene solution was concentrated to approximately 5 mL under a reduced pressure, which was purified by silica gel column chromatography using toluene as eluent. The blue fraction was collected to give 6 mg of 3 (4.2%) after evaporation of the solvent. MASS (MALDI) (m/z): 553 (M++1). Anal Calcd for C29H18N8O1Ni: C, 62.96; H, 3.28; N, 20.26. Found: C, 62.69; H, 3.51; N, 19.95.
As the paragraph descriping shows that 695-53-4 is playing an increasingly important role.
