2346-26-1, Oxazolidine-2,4-dione is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,2346-26-1
solution of 0.5 g (1.96 mmol) of 3-chloro-4-(chloromethyl)-4′-fluoro-1,1′-biphenyl, prepared in step 5.3., 0.240 g (2.35 mmol) of 1,3-oxazolidine-2,4-dione and 0.45 g (3.92 mmol) of 1,1,3,3-tetramethylguanidine in 10 ml of tetrahydrofuran is refluxed for 18 hours. The mixture is allowed to return to ambient temperature and is concentrated under reduced pressure. The residue is taken up in dichloromethane and water and the aqueous phase is separated and extracted twice with dichloromethane. The combined organic phases are washed with saturated aqueous sodium chloride solution and dried over sodium sulphate. Following evaporation of the solvent the residue obtained is purified by chromatography on silica gel, eluting with a 20/80 mixture of ethyl acetate and cyclohexane. This gives 0.33 g of pure product in the form of a white solid. m.p. ( C.): 108-110 C.
As the paragraph descriping shows that 2346-26-1 is playing an increasingly important role.
