Versuchsvorschrift
A solution of 0.1 mol of 4-ethoxy-2,3-difluoro benzonitrile in 100 ml of toluene is slowly added dropwise at room temperature in the course of 30 minutes to a solution of 0.1 mol of aluminium(III) chloride in 100 ml of toluene. The mixture is subsequently heated to boiling for 5 hours and worked up as customary after cooling, m.p.: 145° C.
