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.
