Abstract
Antibacterially effective 3-chloro-2-oxazolidinones are prepared by chlorination of an appropriate 2-oxazolidinone either with elemental chlorine in an aqueous medium or with a mono-, di- or trichloroisocyanuric acid (cyanuric chloride) in an inert organic solvent. The 2-oxazolidinones are, in turn, prepared by reaction of an appropriate ethanolamine either with a di-lower-alkyl carbonate in the presence of a strong base or with urea at an elevated temperature.
