Reaction Steps

To a solution of ethyl cyanoacetate (11.8 g) in acetone (83.0 mL), potassium carbonate (43.1 g) and 1,2-dibromoethane (39.2 g) were added and the mixture was refluxed for 12 hours. After being cooled to room temperature, the reaction mixture was filtered through Celite (registered trademark). The filtrate was concentrated under reduced pressure and further dried under reduced pressure with heating to give ethyl 1-cyanocyclopropanecarboxylate as a red oil (14.2 g).
