(±)-Ethyl 6,7-dimethoxy-1-(1H-pyrrol-2-yl)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate

Abstract

In the title compound, C18H22N2O4, the dihedral angle between the pyrrolyl and quinolinyl fragments is 68.97 (2)°. Two non-classical intramolecular C—H...O hydrogen bonds stabilize the molecular geometry. In the crystal structure, molecules form infinite chains via moderate intermolecular N—H...O(CH3) hydrogen bonds.
