Stork enamine synthesis

Problem # 742

Enamines are similar to enols and enolates in that they also undergo alpha substitution reactions.

The process of performing a carbonyl alpha substitution reaction via an enamine intermediate is called the Stork enamine synthesis. Let's work through this reaction.

 

Draw in the structures for the enamine and show it attacking the alkyl halide to form the  "3º imine." Also draw the structure of the final and carbonyl product.
