 It is also produced by the reduction of benzonitrile and reductive amination of benzaldehyde, both done over Raney nickel.It was first produced accidentally by Rudolf Leuckart in the reaction of benzaldehyde with formamide in a process now known as the Leuckart reaction, a general process in which reductive amination of aldehydes or ketones yields the corresponding amine.Benzylamine occurs biologically from the action of the "N"-substituted formamide deformylase enzyme, which is produced by "Arthrobacter pascens" bacteria.
