Versuchsvorschrift
A solution of 1.6 g. of 5-(2-propyl-3,4dichlorophenoxy)pentyl bromide and 0.22 g. of sodium cyanide were heated overnight at 75°-85° C. in 50 ml. of dimethylformamide. The solution was evaporated in vacuo and ethyl acetate and water were added to the residue. The layers were separated and the organic layer was washed several times with a saturated sodium chloride solution. The organic solution was filtered through sodium sulfate and evaporated to dryness to give 1.38 g. of the desired sub-title intermediate. NMR.
