Production process for 5-alkyl-oxazolidin-2,4-dione
The object of the present invention is to produce a 5-alkyl-oxazolidin-2,4-dione by an industrially advantageous method. The invention relates to novel process for producing a high-purity 5-alkyl-oxazolidin-2,4-dione comprising the steps of reacting a 2-hydroxycarboxylic acid amide with a carbonic acid ester in the presence of a metal alcoholate, thereby completing the reaction in one step, and then isolating the reaction product by a neutralization crystallization method.
