The conversion of 12 into Prozac is carried out
by treating with cyanogen bromide. Propose a mechanism for this
transformation.
It is a name reaction , which is called von Braun Reaction in which a tertiary amine reacts with cyanogen bromide to an organocynamide.
The reaction mechanism is consists of two nucleophilic substitution.
