Procedure
46 g of 3-(6-bromo-1,3-benzodioxol-5-yl)propanenitrile are introduced in portions into 1.4 liters of liquid ammonia in which there is dissolved sodium azide which was prepared previously by the introduction of 16.7 g of sodium into the liquid ammonia. After 30 minutes' contact, the reaction mixture is treated with 38.7 g of ammonium chloride, and then the ammonia is distilled off at room temperature. The residue is taken up in ether and filtered; the precipitate is washed with ether. The combined ethereal phases are evaporated and the resulting residue is recrystallised from isopropyl alcohol, enabling the expected product to be isolated.
