Versuchsvorschrift

A solution containing 4.6 g (0.025 mole) of (4-chloro-2-methylphenoxy)acetaldehyde and 2.1 g (0.028 mole) of glycolamide in 25 ml of tetrahydrofuran and 25 ml of ether was allowed to stand at ambient temperature for 24 hours. The resulting product was washed with 5% sodium carbonate and water, dried and purified by silica chromatography to give 1.1 g of 2-(4-chloro-2-methylphenoxymethyl)-4-oxazolidinone as a white crystalline solid melting at 109°-112°.
