Reaktionsschritte

An internal glass tube was introduced into an autoclave and 0.5 g of ethyl 2-bromo-2-fluoro-1-cyclopropanecarboxylate (cis:trans=0.8:1), 0.5 ml of Raney nickel and 5 ml of ethanol were fed thereinto. Then 0.43 g of 1,2-diaminoethane was further added and the mixture was stirred at room temperature under a hydrogen gas atmosphere (1 kgf/cm2) for 24 hours. After the completion of the reaction, the catalyst was filtered off. Then the reaction mixture containing the title compound was analyzed by gas chromatography. As a result, it was found out that the reaction conversion rate was 100%, the yield was 78% and the cis:trans ratio was 0.8:1.
