1. CN Br 2. LIAIH4 3. H₂O σ NH2 Primary amines can be prepared from nitriles by reduction with LiAlH4. The two-step sequence involves SN2 displacement of halide ion by cyanide ion followed by reduction, and yields a primary amine with one more carbon than was present in the alkyl halide. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions X 2- H-OH NH + OH 2 C
