MECHANISM OF AMINE ALKYLATION
 
Step 1:
The amine N functions as the nucleophile and attacks the electrophilic C of the alkyl halide displacing the bromide and creating the new C-N bond.
alkylation of amines : a simple S<sub>N</sub>2 reaction
Step 2:
An acid/base reaction. The base (excess amine) deprotonates the positive N (ammonium) center creating the alkylation product, here a secondary amine.
