Yield:190970-57-1 91.6%
Reaction Conditions:
with sulfur in water at 40 - 50; for 8 h;Inert atmosphere;Reagent/catalyst;
Steps:
4-5 Example 4
Under the protection of nitrogen, 25g (0.153mol) of (S)-4-phenyl-2-oxazolidinone and 5.2g (0.161mol) of high-purity sulfur In the adsorption reaction flask, drop 87.8g (0.161mol) of 30% ammonia polysulfide aqueous solution at room temperature. After the addition, heat to 40-50°C reaction for 8 hours, sampling of raw materials is less than 0.5%. The aqueous phase was extracted once more with MTBE, combined with MTBE, concentrated, and recrystallized by adding n-heptane/acetic acid (6/1) under heating.Filter and dry to obtain 25.2 g of (S)-4-phenyl-2-oxazolidinthione, HPLC: 99.2%, yield 91.6%.
