With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2346-26-1,Oxazolidine-2,4-dione,as a common compound, the synthetic route is as follows.
EXAMPLE 7 A mixture of 20.2 g. of 2,4-oxazolidinedione, 6.6 g. of paraformaldehyde and 0.1 g. Ba(OH)2 was melted and heated at 90C. for one hour. The melt was taken into 100 ml. methylene chloride and 18.2 g. phosphorous tribromide added at 0-10C. The mixture was let stand at 25C. overnight, the methylene chloride solution decanted and the solvent removed. The residue was washed with water and recrystallized to give 16.7 g. of 3-bromomethyl-2,4-oxazolidinedione; m.p. 63-64C. An NMR spectrum was consistent with its structure. A mixture of 15.0 g.
2346-26-1, As the paragraph descriping shows that 2346-26-1 is playing an increasingly important role.
