Reaktionsschritte
It is known to condense the ethyl ester of 4-chlorobutyric acid with aqueous potassium hydroxide on pumice. There is obtained thereby in moderate yield the ethyl ester of cyclopropane carboxylic acid besides the free acid and γ-butyrolactone (Rambaud, BL. [5] (1938), pages 1552, 1564).
