Versuchsvorschrift

A solution of 13.1 g of 2-chlorophenylacetonitrile and 20.3 g of 1,2-dibromopropane in 142 ml of DMF is mixed with 9 g of sodium hydride (55–65% in oil] at room temperature. It is stirred for several hours and carefully added to water. After extraction with ethyl acetate and filtration by silica gel, the desired product is obtained: 13.1 g
