**Understanding Enamines as Nucleophiles**

An enamine behaves as a nucleophile in much the same way that an enolate anion does, with nucleophilic character at the carbon alpha to the one bonded to the amine. This is because an enamine has resonance structures similar to those observed for an enolate:

- The diagram shows two resonance structures of an enamine. 
  - On the left, the enamine is depicted with a nitrogen atom bonded to a carbon that is also part of a double bond with another carbon.
  - On the right, the resonance structure shows the nitrogen with a positive charge and a double bond between the carbon and nitrogen, while the carbon bears a negative charge.

**Activity: Reaction Mechanism**

With this in mind, draw the complete mechanism for the following reaction:

1. React an enamine connected to a cyclohexane ring with a compound containing a bromide and pentane chain.
2. Then add water with an acidic proton (\( \text{H}_3\text{O}^+ \)).

**Reaction Outcome:**
- The products are a ketone (cyclohexanone with a pentyl substituent) and dimethylamine.

**Task:**
Draw the step-by-step mechanism to show how the enamine reacts to form the products.
