Okay I have this question?  Why is Aniline not considered to be a heterocyclic nitrogen compound?  

is this correct?

A compund containing an acyclic chain and a heterocyclic ring is considered as a heterocyclic compound....an aniline hydrochloride is classified as containing carbon, hydrogen and nitrogen only.



Edit: edited title for better indexing. Mitch

Because Aniline doesn't have it's Nitrogen in the ring.
