2-Butoxy-N-[2-(diethylamino)ethyl]quinoline-4-carboxamide (dibucaine)

The molecular conformation of the title compound, C20H29N3O2, is stabilized by an intramolecular C—H...O hydrogen bond. The orientation of the amide group to the ring system is characterized by a C—C—C—O dihedral angle of 137.5 (3)°. In the crystal, intermolecular N—H...O hydrogen bonds between the amide groups form C(4) chains running parallel to the a axis.
