Reaction Steps

A mixture of 2,2,3,3,4,4,4-heptafluoro-N-[4-(2-cyanoethyl)phenyl]butanamide (3.9 g), sodium azide (3.7 g), ammonium chloride (3 g) and dimethylformamide (60 mL) was stirred under a nitrogen atmosphere and heated in a 130° C. oil bath for 48 hours. Water (300 mL) was added to the hot mixture to dissolve all suspended salts and the solution was allowed to cool to room temperature. More water was added and the precipitate was collected by filtration. The tan solid was dried at 65° C. in vacuo overnight and recrystallized from a hexane/tetrahydrofuran mixture to give 1.9 g (43% yield) of the title compound as a tan solid, m.p. 161°-162° C.
