Task: Please give me a SMILES based on the description below.
Description: The molecule is a nitrosamine that has butyl and 4-carboxybutyl substituents. It is the principal metabolite of the bladder carcinogen N-butyl-N-(4-hydroxybutyl)nitrosamine (BHBN-4). It has a role as a carcinogenic agent. It is a nitrosamine and a monocarboxylic acid. It derives from a N-butyl-N-(4-hydroxybutyl)nitrosamine.
Result: CCCCN(CCCC(=O)O)N=O
