Reaction Steps
Finely ground N-isopropyl valine (31 mmol) in 150 ml dioxane is heated to 38°-40° and excess carbonyl chloride is slowly passed in over 4-5 hours. Dry air is then passed through the reaction for 18 hours, after which the dioxane is removed at 40° (20 mm) to yield 3,4-diisopropyl-oxazolidine-2,5-dione.
