Versuchsvorschrift

A suspension composed of (4,5-cis-diphenyl-2-oxo-3-oxazolidinyl)acetic acid (29.1 g, 97.9 mmol), oxalyl chloride (18.6 g, 147 mmol) and benzene (120 ml) was refluxed for 2 hours. When the suspension became homogeneous, the solvent was distilled off. By the above procedure there was obtained the title compound (30.9 g) as light brown oil.
