Preferred Abstract (Original):
The title molecule, C16H19ClN2O2, contains three planar
fragments, i.e. the quinoline system (A), the butylamino group
(B) and the carboxyl group (C). Angles A/B and A/C are
9.1 (2) and 79.08 (4), respectively. The alternation of the
bond lengths in the quinoline bicycle correlates with literature
data.
