ABSTRACT:
The condensation of an .alpha.-halogen carbonyl compound with carbamic acid esters in the presence of a basic condensing agent and an aprotic solvent enables the production of oxazolinone-2-compounds in a high degree of purity, and in high yields in one step by using simple and readily available starting compounds.
