Komponenten

Versuchsvorschrift

A mixture of 1-bromobutan-2-one (7.2 g, 47.7 mmol), sodium benzoate (7.56 g, 52.4 mmol), and N,N-dimethylformamide (72 ml) was stirred at room temperature for 3 hours and 45 minutes. Diethyl ether was added to the reaction mixture and the mixture was washed with water and a saturated saline solution, dried over magnesium sulfate, and filtrated. The filtrate was concentrated under reduced pressure to obtain the title compound (9.5 g, quantitatively) as a light brown oil.
