695-53-4,695-53-4, 5,5-Dimethyloxazolidine-2,4-dione is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A mixture of naphthalene-2,3-dicarboxylic anhydride (0.158 g, 0.8 mmol), 2 (0.104 g, 0.8 mmol), anhydrous NiCl2 (0.104 g, 0.8 mmol), urea (0.337 g, 5.6 mmol) and a catalytic amount of MOA was stirred in boiling sulfolane (3 mL) under argon for 1 h. After cooling to room temperature, the reaction mixture was diluted with water. The precipitate was filtered off and washed with hot water. After drying, the crude residue was reprecipitated from H2SO4/H2O, and the resultant precipitate was filtered off followed by the washings with hot water until the washings became neutral. The crude residue was extracted with ethanol and then trichlorobenzene. The trichlorobenzene solution was briefly passed through a short neutral alumina column, and the concentrated to ca. 5 mL under a reduced pressure. The precipitate was induced by adding hexane, and the obtained solid was recrystallized from trichlorobenzene/hexane to give 7.5 mg of 6 (6.4%). MASS (MALDI) (m/z): 702 (M+).
The synthetic route of 695-53-4 has been constantly updated, and we look forward to future research findings.
